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.

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

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.
