New Net Name System Mired in Controversy


New Net Name System Mired in Controversy
By BEN ROONEY

If you want to own your own top-level domain you have until Friday to submit your application (along with the $180,000 fee). Once the deadline passes, that is it for the foreseeable future.
The original closing date was April 12, but this was extended had to be to be extended by the Internet Corporation for Assigned Names and Numbers, or ICANN, the Web's names regulator, after it found "unusual behaviour" in its systems.
The most dramatic shake-up of the internet's naming system could see the introduction of over 1,000 new "top level domains". Top-level domains (TLD), as the name suggests, refer to the very top of the Internet's naming system and include the 22 generic TLDs such as .com, .org and .net. They also include the 250 or so country code TLDs (such as .fr for France, .de for Germany or .ru for Russia).
Last year, ICANN agreed to throw open the naming convention, so that anyone with the money, the technical expertise and the ability to prove their competence can own any new TLD. The plan is to allow the introduction of the so-called ".brands" so that, for example, Apple AAPL -2.82% could purchase .apple (rather than www.apple.com). More generic extensions, such as .music, .web, .beer, .pizza and .sport are also available.
When new registrations closed on March 29, there were 839 registered users on the system; a user can apply for up to 50 domains. ICANN will announce the details of the process in the week beginning April 30.
The plan to open up the naming system has been mired in controversy. The U.S. Association of National Advertisers sent a petition to U.S. Commerce Secretary John Bryson expressing "strong concern" about the proposals. "ICANN's action was taken despite widespread and significant objections raised throughout the process by many in the global community of internet users," the petition said.
Signatories to the petition included Adobe Systems, ADBE -1.10% American Express, AXP -1.31% Burger King, Coca-Cola, KO -0.39% Dell, Ford Motor F -1.24% Company, General Electric GE -2.18% Company, Hewlett-Packard, HPQ -2.11% Johnson & Johnson, JNJ -0.95% Procter & Gamble PG -0.42% and Publicis Groupe PUB.FR -2.08% .
However, Peter Dengate-Thrush, who was Chairman of ICANN at the time the organization was steering through the changes (he stood down in June 2011), stood by what ICANN had achieved. "It coming up to a year since I left. I don't think there is anything that we could have done, or should have done differently about the process. It was an unprecedented set of negotiations between the board and the governments of the world."
The move also angered the U.S. government. ICANN's application to the U.S. government's National Telecommunications and Information Administration to renew the contract to run the Internet Assigned Numbers Authority, which underpins the internet's numbering system, was rejected on March 9, even though ICANN was the only applicant. The contract has been temporarily renewed until September.
Although he no longer speaks for ICANN, Mr. Dengate-Thrush said the failure to renew the IANA contract was not a significant issue. "I am reasonably confident that ICANN will end up running the contract because ICANN has been built by the international community to do its job.
"[I] Just see it as a reasonably straight-forward commercial negotiation between parties to get to where they want to. It is not a threat to ICANN. The threat to ICANN would be if the global internet community said we no longer want to use the ICANN process as the forum for developing internet policy. ICANN's job is to make the policy for allocating addresses.
"One of the points the US Department of Commerce raised was functional separation, so they might want a bigger firewall between the policy work that ICANN does, and the implementation work it would do with the IANA contract."

Twenty Percent Of American Adults Never Use The Internet
Author: Jessica Grabert
With the Internet widely available for use in homes, schools, and in public spaces like libraries, one would think nearly all of the American population would have at least checked out the Internet at least once or twice. Turns out, reality is much farther from the truth: according to The Pew Internet Project, one in five American adults never go online.
If babies and maybe puppies were involved in this equation, the numbers would be a little less shocking, but since we are only talking adults, the figure is far more harrowing. According to the study, most of the adults who do not use the Internet live in households where no one uses the Internet. Even more problematic, most responders to the study have no interest in any online activity, stating the Internet is not useful or has no germane content.
The news is not all bad, however. Despite the issues still present with the digital divide, Internet use is increasing across the board. According to eWeek, in 2011, only about half of Americans had Internet access and now 62% have the much faster broadband access. Now, even lower income groups and those with no college education have been increasingly using the Internet, mostly due to the wide availability and easy access of mobile devices.
Despite the obvious presence of a digital divide, the numbers are certainly improving. If you flip them on the head, the glass is even half full.

As if Nokia Lumia 900 Windows Phone didn't have enough problems
Nokia has enough Lumia 900 marketing problems, without twitter making more. The photo with this post is pretty self-explanatory and shows how nasty promoted tweets can be.
The smartphone went on sale from AT&T April 8 for $99.99 -- that's quite a good price. Then almost immediately users started complaining about Internet connectivity problems, and Nokia quickly responded by making a magnanimous offer: $100 back to the people who already bought the phone and were willing to install a software update. Anyone else: Phone replacement. Meanwhile, Lumia 900 is free to new buyers until April 22. Okay, so why is there a promoted tweet in my feed on April 15: "That's right!"
Sure, it's a March 26 tweet, but there's no place for such an offer when the phone is free nearly three weeks later. Many people won't look at the date stamp. Small plus: Customers expecting to pay 100 bucks but finding the phone costs nothing once at AT&T. They should be happy campers. For others familiar with the temporary free offer, there could be confusion and reprehension.
I don't know how these promoted tweets work, so it's all a mystery to me. Would someone more knowledgable than me like to explain this?

Soldier Crabs Used to Create Computing
By David Murphy
No, the next computer you purchase isn't going to be powered by crabs. Nor will any physical computer on this Earth likely construct its logic from a series of slow-moving crustaceans.
But that's not to say that it's impossible to do so.
Researchers at Japan's Kobe University and the United Kingdom's University of the West of England have conjured up a system for defining computer logic based on the real-life movements of a bunch of crabs. Soldier crabs, specifically, whose natural tendency for swarming can be exploited in a maze-like environment to serve as living representations of AND, OR, or NOT functions.
Lost yet? Here's how the experiments worked: The researchers first built a series of gates – two "walled" tunnels that fed into a single walled tunnel. Crabs would be placed into each of these walled tunnels and, as a result of their natural movement, follow the walls up to the point where both combined into one. The crabs would then combine their individual swarms – and velocities – and continue down the new, single tunnel.
In other words, the crabs recreated an "OR" function: The two tunnels the crabs were first placed in are analogous to saying, "Show me pictures of kitties or puppies." And the merger of the "kitty" and "puppy" tunnel would be the direct result of the query, which the crabs – analogous to data – would walk down.
The researchers found it a bit trickier to replicate the experiment with an "AND" gateway – two paths converging into one, with the crabs ideally ignoring two other paths representing the outputs "NOT AND" as well as "AND NOT." They didn't go quite as great a job on the "ignoring" part of the experiment, but the researchers believe that results can be improved, "by creating a more crab-friendly environment," writes Wired's Olivia Solon.
The crab experiments are the biological equivalent of billiard-ball computing, or the idea that the collision of balls and walls (assuming they never lose energy) can mimic various computations. The crabs needed a bit of a head-start in their computational sessions, however. Researchers used shade, or the crabs' natural fear of birds swooping down to eat them, to encourage the crabs to get computing.

Cheap charger is damage, cell phone power management need to be cautious A

Cheap charger is damage, cell phone power management need to be cautious A


The market has been sold for several dollars cheaper charger, and some cottage charger configured only cost a few dollars. These low-quality cell phone charger to ensure it? Safe? How do they save the cost of it? Saying "you pay for," Although today is not entirely correct, however, mobile phone charger market, it is still the truth. Here, you will be lifted some of the secrets of cheap chargers, and chargers to prevent the harm of these low-cost, mobile terminal power | regulator management program must be a preventive measure, can not cut corners to save costs, or else.


Causes of poor quality and hazardous charging device


MPS Asia Marketing Director Yuan Wenlin: complete charge management and protection should be divided into three parts: the charger end, the host side, the battery pack. The protection of their respective a chain, are indispensable.


Yuan Wenlin: Many markets sell the cheap charger may only use a simple winding transformers, there is no such over-voltage over-current protection.


Chargers are generally divided into Switch (switch type) and Linear (linear), with many markets selling cheap charger for profits, may only use a simple winding transformers, there is no over-current protection of overvoltage etc. also not taken into account such factors as power supply stability, the potential risk to bring the phone itself. Because mobile phone manufacturers can not predict whether its end customers to use only qualified charger charging the host, so many international brands in order to protect its reputation and reduce the cost of repairing the sale will charge the phone line plus a front-end chip protection .


State Ministry of Information Industry in 2007 by the introduction of handheld mobile communications standard charger, mobile phone manufacturers have specifically requested additional input over-voltage protection function of the host side, but the market many companies to cut costs in shipping in volume after shipment application on the network canceled the certificate was used by the overvoltage protection chip. At the same time, the battery pack side, cancel the NTC should Dianchi package over-temperature cold Baohudianzu the battery core temperature changes Wufajishi charge feedback Ji Guan Li chip, Zhe gave end users were in charge when the charge Xian Lu Dai Lai light damage , shortened battery life; serious cases such as the battery explosion / fire and other potential hazards.


Texas Instruments | Instruments high-performance analog business development manager Zhang is: from the charger side, the biggest problem is the use of optocoupler, transformer insulation is not absolutely reliable, and if to save money, poor quality of materials used, there greater safety hazards; second no-load power consumption too, and now the mainstream requirement is less than 300mW, the Japanese have begun to demand 150mW; third point is that consistency is poor, after the exchange of different adapters can not guarantee applies.


Zhang was: Some mobile phone charger management software by relying, in the event the software errors that may result in accidents and disasters.


From the host side view of a number of mobile phone charging management function from the power management chip alone PMU completed, or anyone else for the single-chip integrated baseband, which charge related work all rely on PMU or the baseband chip to implement the software. While the cost is low, but the software dependent on, if there software errors may cause unexpected disasters; on the other hand, CPU Built-in rechargeable management functions, as process constraints often can not be achieved with higher input voltage, so when the user use of poor quality, or charger, plug the charger because the surge voltage generated all possible PMU or damage to the baseband chip, this time through the software to achieve many of the protection functions are not working, may have unpredictable consequences; s Third, a number of built-charge management can only be achieved and the average pulse current charging current management, the peak current limit is to rely on the charger itself, which may cause the battery life is too short, use of public phones in the future exchange of appropriate different adapter also will be hidden after.


Saint-state microelectronics product line manager, Lu Liang: charger as the product of accessories, competition, cost too much pressure, there will be more hidden than the host side. There are usually indicators of performance and product description does not match, or the electric strength failed. Dielectric strength is the charger product safety assessment of important indicators. If consumers choose such a product, electric shock may occur, threatening the personal safety of consumers.


Security measures


PI, senior vice president Doug Bailey: There are three safety hazards battery charger, or electric shock, fire and damage to the environment.


Doug Bailey: the existence battery charger electric shock, fire and safety hazards and environmental damage.


Security design approach is to supply the high side and low side to maintain the appropriate insulation and between the gap. International Electrotechnical Commission (IEC) of the rules covering the safety of power supply design, there are many security agencies in monitoring production standards.


High quality products include thermal shutdown function, disconnect the power when the charger overheating; also has over-current shutdown feature, you can short-circuit the battery (which may lead to heat and fire) will power down to about 1% of rated power. Through the use of efficient control algorithms, and to ensure that products are free of halogen and PVC to minimize harm to the environment. These algorithms ensure that the charger in the power consumption of non-minimum state of charge.


Texas Instruments high-performance analog business development manager Zhang is: a new generation of mobile charge management chip requires the following characteristics:


Higher pressure, typically 18V ~ 26V; path management function, independent of charge and system power path path; thermal management capabilities, once the chip core temperature rises to a certain point automatically reduces charge current to ensure the safety of the system; LDO function, when the battery is not installed can boot the system, which is especially suitable for debugging or production test, certain occasions such as wireless public telephone, the battery may not be standard when it comes to cost.


USB charging power needed to meet the USB IF standard, low-power power supply 100mA, high-power power supply 500mA; Furthermore, a switch-mode charge will maximize the use of USB port 2.5W maximum power consumption.

Industrial battery industry market

Industrial battery industry market


The gap between technology and manufacturing a profound impact on the market, industrial battery industry


"The more you look, the less you know" is no doubt we are in the process of writing this report most experience.


We have been thinking, what is the power of the battery industry? We believe that every application of new materials for a qualitative leap in battery performance, each anode and cathode materials also contributed to the improvement or electrolyte batteries have a certain level of quality improvement.


History of the battery, it is a material advancement of technology history. Quantitative improvement of the battery technology, the invention of new materials to promote qualitative change in the battery. Can be expected, the use of conductive material containing the element lithium (ionic compounds, polymers) as the electrode material is the best choice for high-energy battery, but, multi-element compounds found in lithium-ion materials technology needed to continue to progress.


Enhance the energy storage potential, improve energy density, this battery technology is always evolving concept of one of the most direct. However, the perfect person does not yet exist, especially for high power and high energy is difficult to have both. Moreover, we will find that different products have diverse needs of the battery.


Thus, the development of battery materials is diverse.


Contrast the appearance of performance, safety, price, life are all indicators must be considered, which determines whether certain widely used battery. Because, superior performance lithium-ion battery, different cathode materials for lithium ion batteries to meet the cost differences between market demand for different applications, therefore, the formation of lithium-ion battery cells for other types of alternative trend is almost full.


Despite our impression that the battery is labor-intensive manufacturing, but the battery industry chain from the point of view, is also a technology-intensive, especially in resource mining and processing and battery materials preparation more involved in materials science. Lead-acid batteries through the icon, nickel hydrogen batteries, lithium-ion batteries manufactured by the main process areas, we pointed out the direction of development of the domestic battery industry and technical bottlenecks.


In the battery industry, China and Japan, there is a considerable gap between the United States, which ultimately can be reflected in the materials technology gap between the domestic and foreign industry. We believe that relying on imports of battery materials, the manufacture of small single cells are mature; But even solve the problem of battery materials, high-capacity high-power battery pack design and manufacturing continues to face many problems, which is the electric vehicles battery technology needs to break the key technical difficulties.


Business transformation from the perspective of the development of China Battery, Lithium-ion battery industry competitiveness in the market depends heavily on the accumulation of long-term development of the technology, rather than pure capital investment, and similarly, lithium battery materials with high technical barriers, the small sub-industry leaders who are mostly early entry into the industry. However, the small lithium ion battery business, technical threshold is low, the influx of a large number of small participants led to the rapid decline in industry profitability.

Lithium iron phosphate battery and Electric cars

Lithium iron phosphate battery and Electric cars


December 17, 2008, in "FPT Fiat Powertrain Technologies Cup cars Gold List of new energy technologies," the award ceremony, 863 new energy vehicles, head of major projects Mr. Wang Binggang advice about new energy in the vehicle development, said the world will celebrate the rechargeable electric cars and hybrid vehicles a period of rapid development, China will put the two technologies included in the national auto industry development of industrial revitalization plan.


Wang Binggang In particular, the development of electric cars advantages: all the energy can be transformed into electrical energy, its production process with a high concentration of carbon dioxide emissions and easy storage solution, and has high energy conversion efficiency.


Statistics show that the general household vehicle mileage less than 100 km on the probability of about 66%. Wang Binggang everyone calculations: If the estimated 20,000 km of driving, with petrol car fuel consumption of 10 liters per hundred kilometers, and oil prices 6 yuan / L account, then use the fuel costs of 1.2 million; to hundred kilometers of electric vehicles power consumption of 15 kwh and electricity price of 0.5 yuan / kWh, the annual use of electricity is 0.15 million. Batteries, if the design driving range of 150 kilometers, 15 kWh / total power consumption per hundred kilometers, you need 22.5 kwh of the battery, the battery than the price of 1.5 yuan / kW, the battery price was 34,000 yuan. Even so, electric cars than gasoline cars to save fuel costs each year about 1 million, 3 to 4 years to offset the cost of the battery.


For rechargeable hybrid vehicles, Wang Binggang clear that, plug-in hybrid technology to extend the driving range of electric vehicles, which usually use electric drive, while driving long distances into the hybrid state, is very suitable for China The.

Experts from Tsinghua University Professor Song Jian Wang Binggang endorsed the view, he also believes that the most promising applications of electric vehicles is the plug-in, because it greatly reduces the battery capacity.


Professor Song Jian analysts say China's current electricity and oil units of energy from the perspective of almost the same, gasoline is 6 yuan / liter, electricity is 0.5 yuan / kWh, 12 kWh basically in 1 liter of oil, energy are equivalent. But electricity is a secondary energy, it is used in the car can reach 80% conversion efficiency, compared to 12% fuel conversion efficiency of 16%, almost 5 times the difference. In the premise of equal energy consumption to 20% of the price to obtain the same effects with petrol vehicles is the plug-in car selling point, that the cost of its use significantly declined.


Song Jian, also pointed out that commercial development of electric vehicles is still a major bottleneck in the cost. At the same time, high-performance motor and controller unit price of power is basically 3 times the price of the current internal combustion engines, but also hinder the commercialization of electric vehicles, the main factor. In addition, like braking, steering, air conditioning and other electric vehicle-specific parts, which company has yet to develop a sophisticated use of compressed air in the vacuum booster system, the electric car air-conditioning there are voltage matching problem, these are the electric car industry to make efforts to solve the process.


Song Jian that the lithium iron phosphate stands to reason that the cost than lead-acid battery is lower, its target price should be three to five cents one kwh, now a key factor restricting its development process is due to low yields caused by premature . Song Jian said that if the yield of lithium iron phosphate can be increased to 90%, will reduce the cost of making it to the current one-twentieth or so, its prospects will be very bright.

PV market in China

PV market in China


China is the world's fastest growing economy in the country, with the increasing depletion of global fossil energy, domestic energy supply and demand have become increasingly tense, development and utilization of renewable energy is to advocate and support our government ease the energy supply and demand in the most effective way to tension .


Include solar thermal solar, photovoltaic photovoltaic huge industry. Solar photovoltaic power generation is a completely zero emission clean energy, but also a reality close to the energy scale applications. Photovoltaic power generation has many advantages, such as: safe, reliable, no noise, no pollution, energy widely available, without geographical restrictions, no consumption of fuel, no mechanical moving parts, low failure rate, easy maintenance, can no duty, construction Station cycle is short, the size of random, without erecting transmission lines, can easily combined with the building and so on. These advantages are the conventional power generation and other power generation methods can not reach.


Remote desert areas of virgin land PV market


According to Trina Solar CEO, who introduced high-century, China has a vast, complex geography, especially in Tibet, Xinjiang, Inner Mongolia, Yunnan, Guizhou and Sichuan is located in the remote and desert areas, abundant solar energy resources, use of solar photovoltaic products to address local difficult problem of electricity should be one of the best.


He said that China's large tracts of desert, desertification of land and potential desertification land, totaling about 105 million square kilometers. According to one square kilometer of land can be installed 100MWp solar calculations, 1% of the desert can be installed 1000GWp, China's installed capacity of 2 times the current power, and this area of photovoltaic power generation applications now account for only 0.2% of the market. Therefore, this is a huge untapped virgin territory.


Boost the development of local PV market


Since 2007, the international situation changing economic situation in the foreign market crunch, the domestic photovoltaic companies for enterprise survival and development in the Pathfinder. Also brought good news is that the local government and relevant departments are also active in action, for the PV market expansion in the domestic enterprises build bridges.


It is understood that in Beijing, Shanghai, Hefei, Shenzhen and other cities, more and more energy-efficient demonstration area, solar lighting projects are government procurement, the Government will pay for solar energy products. In the promotion, many solar companies are good and government form a "coalition forces", with government action to further market their products and make a reputation. It is reported that the construction of solar Chuzhou Rongshida full solar mining group in the local ecological community has no small reputation, Rongshida for this project provided all of the solar lighting system, a model and win in Jiangsu, Hubei, Henan, to order. Government PV business development help.


Shanghai Municipal Economic Commission, Changsha City Energy Office and other government departments are the green lighting, wind and solar energy technologies and other new projects included in the key energy conservation projects in the city, and municipal road construction, landscaping in the large-scale promotion. Shanghai in 2007 to create a number of energy-saving model for example, photovoltaic power, solar lighting will be fully applied in these projects.


PV industry in China, Jiangsu province, began organizing the implementation of key development and application of solar energy utilization technology demonstration projects, in order to Suntech, Changzhou Trina Solar, Nanjing electricity companies represented, fully utilize resources advantages for the big clean energy industry continued efforts.


Solar photovoltaic become a real estate development "selling points"


In recent years, solar energy into building components of housing facilities and residential communities, has become the consensus of many real estate agency, real estate, real estate developers are beginning to realize the use in the development of new energy brings added value to the project.


A city called "Paris in the spring," the one-time real estate 31 a smooth delivery of residential buildings, the value of several million dollars to install solar photovoltaic systems contributed to environment protection and energy of solar power generation facilities has become the biggest selling point of the real estate. Photovoltaic power generation is not only energy but also a good way to boost sales, the developer will invest more than 500 million residential electricity for lighting all converted into solar power systems. Although much has invested several million dollars, the price per square meter of housing up so two to three hundred dollars, but consumers are interested in the use of new energy sources, sales all the way to good.


In Shenzhen, Dongguan, Nanjing, Xi'an and other places of the developers, have begun to hand photovoltaic enterprises, the introduction of solar lighting system real estate industry.


Although the State introduced the "Renewable Energy Law", has not yet issued specific PV-specific incentives, but local governments in the development of advantageous resources and create a harmonious environment has been some movement, which is the market development of PV business significant.


Experts interpret domestic PV market


In recent years, in the international market and driven by domestic policy, China's PV industry has emerged in many excellent photovoltaic production enterprises. China has become the world's three major producers of photovoltaic cells. According to experts, China is in the following areas to promote the domestic PV market development:


One. Is to start sending electricity to the village projects to solve the electricity problem the village without electricity. Currently, the World Bank, the National Western Development Office is doing the program.


II. A special project on the use of photovoltaic power generation, such as the World Expo, the Olympics.


III. Is the construction of photovoltaic power plants in desert areas.


IV. Are prepared to mobilize a number of cities, start roof plan, and now, Shanghai, Beijing, Baoding, Hebei, Shandong, Texas, are exploring this issue.


Five. Is the study of the development to improve the competitiveness of PV electricity price policy.


According to high-Ji Fan, China's current largest PV market is still the area of communications, including microwave relay stations, satellite communications ground stations, satellite TV receiving poor transfer system, program-controlled telephone exchanges, military communications stations, etc., the current market share of around 50% .


China's huge market potential of solar PV, solar companies can seize the opportunity, beachhead, we will wait and see!

Lithium Battery Energy saving Upsurge

Lithium Battery Energy saving Upsurge


With the constant fluctuations in international oil prices, energy saving environmentally friendly lithium battery in the limelight once again a hot topic. From 6 months, the number of international auto companies and electronics companies are using large-scale lithium battery joint investment. Including Toyota and Matsushita, Nissan and NEC, Volkswagen and Sanyo, Bosch and Samsung, they believe that lithium batteries in the next few years will gradually replace the nickel-metal hydride batteries, lead the direction of development of hybrid vehicles. Li-ion battery in the heat of global investment background, China's automotive enterprises in this research work is in what kind of? Experts on the lithium battery is holding what kind of attitude? Recently, the reporter interviewed specifically on this issue who has studied the domestic lithium battery, several experts.


Beijing Institute of Electric Vehicle Engineering Center Deputy Director Lin Cheng


Study of lithium iron phosphate has been a breakthrough


Lin Cheng told reporters, demanding automotive lithium batteries. It requires that the vehicle used in a variety of conditions, must protect the security, can not occur fire, explosions and other accidents. The first was for battery electric vehicles, in this country has made great breakthroughs have begun to take industrial scale. But 5,6 years ago, with the battery powered vehicles are often some accidents, such cells will gradually be diluted. Now, the domestic lithium battery research progress quickly, especially in the battery safety issues, has made great progress.


Lin Cheng told reporters, lithium batteries include lithium manganese oxide and lithium iron phosphate batteries. At present, the development of the domestic lithium manganese oxide has begun to take shape. Lithium iron phosphate as safer, longer life, will become an important direction for future development of lithium batteries, but also abroad, the focus of research and development of the automobile. At present, lithium iron phosphate studies of good progress, especially in some of the patent on a breakthrough, this time for the Beijing Olympic Games is a passenger car with a self-developed lithium iron phosphate lithium battery.


"Of course with the study abroad compared to lithium batteries, the domestic lithium battery research still lags far behind, but the domestic lithium battery emphasis on increasing, the future will be the R & D focus." Lin Cheng told reporters.


Henan Huanyu Group lithium battery industry technology Deng Lun-ho, deputy chief engineer


Large-scale lithium batteries for electric cars need some time


Henan Huanyu Group is a component from the battery to the battery cell manufacturing plastics and related hardware, equipment manufacturing, electronics manufacturing, a complete industrial chain of the Enterprise Group, has undertaken the project of Science and Technology Li-ion battery research and development.


"At present the domestic lithium battery research and abroad, the gap is mainly reflected in the battery control system and power management systems." Deng Lun-ho told reporters that now the domestic lithium battery research for development in their respective state. Currently, some companies have been able to provide the corresponding lithium battery electric vehicle accessory products, supporting the general lithium batteries can run 200 to 500 km.


Deng Lun-ho told reporters that now the price is too high the domestic lithium battery, power management system problem has not yet been well resolved. Charging electric vehicles also face the problem. Currently, the general line at home can not charge lithium batteries for electric vehicles must be equipped with a small dedicated charger, and charging time is very long and very troublesome. Abroad, in order to solve this problem, generally regarded charging stations and gas stations together. China is now charging stations have not established a large scale.


Deng Lun-ho believes that the current consumer acceptance of electric vehicles equipped with lithium batteries it still more difficult: "the price of an ordinary electric car is about twice the same configuration or even higher gasoline locomotives, domestic consumers have not enough economic prepared to accept the power and electric vehicles. "


China Electric Power Research Institute engineer Chuang Feng


Optimistic about the prospects for the development of lithium iron phosphate


Chong Tong, told this reporter, the electric vehicle battery research and development work has gone from lead-acid batteries, nickel-metal hydride batteries to the development of lithium batteries, each battery advantages and disadvantages.


The earliest to appear in lead-acid batteries, used in the longest time, belonging to the battery series. The best safety performance lead-acid batteries, rare explosion, fire and other phenomena, energy storage effect is not ideal. Later, people developed a nickel-metal hydride batteries, store energy and power than the effect of the ideal lead-acid batteries, but due to nickel-metal hydride battery in the charging of hydrogen generated in the process prone to explosion, so the nickel-metal hydride batteries in a business may or may not state.


To the year 2000, people developed a lithium battery. Lithium batteries are lead-acid storage battery of power 2 to 3 times, but because it contains lithium-ion active in the metal layer surface, prone to spontaneous combustion in the air, explosions, etc., higher risk. So now the major countries is to control the development of lithium batteries is safety and stability.


"Charging a lithium battery would be able to cycle around 1000, in which the stored energy of lithium iron phosphate is better than lithium cobalt oxide and lithium manganese oxide effects worse, but it's the best safety performance, than lead-acid battery energy storage much higher, so now the most promising lithium iron phosphate. "Chuang Tong said.


Society of Automotive Engineers of China, director Chen Quanshi branch of electric car


Three problems of domestic lithium battery research


Quan-Shi Chen said in an interview: "Now the state attaches great importance to the study of lithium batteries, '863 'project, the state invested a total of 66 million yuan, all development work for the lithium battery. We and Japan, the United States such as walking in the lithium battery research and development in the forefront of the developed countries, China's lithium battery manufacturing precision, equipment, standards, etc. there is a certain gap between R & D details.

Quan-Shi Chen told reporters that at present there are three issues of domestic lithium battery research. The first is the consistency of manufacturing. Since the lithium battery manufacturing technology and equipment there is a gap, the domestic lithium battery production technology mixed, manufacturing standards has not yet reached agreement. Lithium batteries used in electric vehicles are connected in series or in parallel, if the consistency issues are not well, then the large-scale production of lithium batteries used in electric vehicles will not be able.


Followed by the intellectual property rights. Currently in the study of lithium iron phosphate has made a breakthrough, but the U.S. patent in this area, so although some of our links to independent research and development, but in intellectual property issues, but also do not know how to respond.


The third issue is the selection of raw materials. Now the production of raw materials used in lithium batteries can not all imported, mainly from China, but domestic raw materials, through international certification, to produce lithium-ion batteries in order to be internationally recognized, so the link in the certification of raw materials and also some problems.

Buffett's largest battery manufacturers Nuggets storm

Buffett's largest battery manufacturers Nuggets storm


Subject to further deterioration in U.S. subprime mortgage crisis news, global stock markets plummeted again, almost all of the investors are confused and do not know how to develop late, and which concern the industry, this time, "Warren" Buffett once again shot for specified investors the future direction of investment. Hong Kong-listed BYD at the opening day last week, rose 90%, almost double! The reason is that Warren Buffett invested 1.8 billion Hong Kong dollars acquisition of China's largest rechargeable battery maker BYD stake of 10%! Currently, the market authority generally agreed that the field of BYD electric vehicle battery technology leading the main advantage is one of Buffett's shot. It is noteworthy that, in Buffett's BYD to attract investment and short-term stimulation soared, A-share market after the opening bell on Monday to Section power far, Desai batteries, battery, led by market trends limit the outbreak of the collective subject shares , one of the few bright spots the market. Their common characteristic is the same as the production and BYD car battery! After careful excavation, we found (000,839) CITIC Guoan: The company is the largest lithium battery cathode material of lithium cobalt oxide and lithium manganese oxide manufacturers, but also the only large-scale domestic production of lithium ion secondary battery manufacturers, Power Battery Company has been identified as the 2008 Beijing Olympic Beijing Olympics pure electric bus exclusive supply products, we can see whether a product or a scale far better than the BYD, Section Desai battery power far and is worthy of the name power battery industry leader, therefore, short-term effect in BYD under battery power crazy, and Buffett's long-term gold investment philosophy is driven, we have reason to look forward to CITIC Guoan up the outbreak of the future will continue to strongly recommended that investors pay close attention!


Buffett storm Nuggets, car battery to prominence!


In a jittery global financial markets when, "Warren" Buffett once again dished out generous, indicating their car battery industry is very promising. Authoritative analysis revealed that Buffett will focus new energy battery new energy industries, especially the nickel-hydrogen batteries for automobiles into a stimulant. BYD resumption of trading last week after Hong Kong stocks, the stock doubled in 3 days, attracting the attention of the world. In addition, the National Energy Research Institute Master Ren Gaoshi constitution that the Government to promote and encourage the development and utilization of new energy policy will not change. This means that the growing tension in the energy and long-term trend, domestic battery and other items with the listed company full of bright prospects for development. And because of this, A shares within the first trading day National Day Return staged a crazy battery subject shares soaring drama, we see a continuous plummet in Shanghai and Shenzhen panic atmosphere, with car battery Aspect of the Division real force far stronger limit Desai batteries, such as production Fosugufen related materials are nickel-hydrogen battery to soar! We note that the focus of BYD soared because of its battery Aspect, A-share market is currently involved in the field are not many listed companies, only a few have a true sense of the power battery products projects. This background, as a real car battery Aspect (000,839) CITIC Guoan is unknown at present, there will be a blockbuster material afternoon soared good show!


The largest battery manufacturers, the industry leader!


CITIC Guoan MGL (referred to as MGL) CITIC Guoan Co., Ltd. is holding 90% of the subsidiary. MGL was founded in April 2000, mainly engaged in the lithium ion cell materials and high energy density lithium ion battery research and development, production and sales. MGL is currently the largest lithium battery cathode material of lithium cobalt oxide and lithium manganese oxide manufacturers, but also the only large-scale domestic production of lithium ion secondary battery manufacturers. After nearly a decade of efforts, MGL has developed into a business involved in technology development, production and sales and investment and other aspects of comprehensive large-scale high-tech enterprises, and formed from the lithium battery materials and lithium batteries to electric vehicle research and development and production complete industrial chain. MGL power lithium battery for 5 consecutive years by a national authority comprehensive security and performance testing. Outstanding safety performance of the product, MGL developed high-capacity lithium manganese battery by the Beijing Organizing Committee for the 2008 Beijing Olympic Games to determine the pure electric bus exclusive supply of products. Requirements under the Beijing Municipal Science and Technology Commission, CITIC Guoan MGL Power Co. electric car project for the Beijing Olympics provided 100Ah high-capacity lithium manganese battery loading has been running for more than 10,000 km, the battery in good working condition. It is reported that electric bus charging time is short, 3 hours to reach 95% charge level, charging each one to run 200-400 kilometers per charge and 500 times the battery capacity will decay by 8.3%, its operating cost is only fuel vehicles 1 / 5. Lithium manganese oxide as cathode in the large-capacity secondary battery power, is expected in the future will quickly be applied to the land, sea and space and other mobile power, emergency power, uninterrupted power supply and large-scale power storage device in the city at night. CITIC Guoan MGL Power Technology Co., Ltd. has developed several hundred to several kilowatts of energy boxes of new products, take advantage of non-renewable energy create a new way. It can be seen, as with BYD's battery, the company's battery subsidiary and use the product even better, and many other aspects, which had people on the CITIC Guoan is more optimistic about future prospects, a real The industry leader!


If you are confused to believe that Buffett's eyes!


In a jittery global financial markets when, if you lost to believe that Buffett's eyes! God shares the success rate of at least much higher than other institutions, so time and time again history proved Buffett's unique vision. Market, the Hong Kong-listed BYD opening day or 90%, almost doubled; A-share market point of view, with real car battery Corun Aspect, Desai batteries continuous limit, such as production Fosugufen nickel-hydrogen battery related materials are substantially higher. This background, we believe, CITIC Guoan is the largest battery manufacturer, the company battery is identified as the 2008 Beijing Olympic Beijing Olympics pure electric bus exclusive supply products, we can see whether a product or size are much much better than BYD, Section power far and Desai battery, battery power is truly the industry leader, the bottom of the stock price is still in the history of power sector will attract the coveted. Technically, the stock adjustment in place, is expected to strongly broke up late, it is worth investors to pay attention!
