Battery base, with days can ZhangTianRen board chairman group China’s new energy battery prospects, to communicate and vice President, vice President YangYuanLing group RenAnFu engineer, chief investment officer WangZhiKun and Chinese famous electrochemical expert dr gaoping cao join the discussion. Academician Yang, from the country, and that the national interests and the economic development of China’s new energy to consider global development of batteries. Lithium battery of future development foreground is very good, but the existing main problems are battery and safety of lead-acid batteries, electric cars and storage in a battery, the key is to continue to do technical progress and environmental protection work.
Lead-acid batteries, can have a new life
Academician Yang, lead-acid batteries, and experience 150 years of nickel cadmium in batteries, nickel hydrogen battery, lithium ion batteries battery listed as one of the few decades, still can firmly occupy most of market share, Our electric bicycle with nearly 200 million vehicles, most with lead-acid batteries, The world of internal combustion engines, each one with a piece of lead-acid batteries, it is no accident. Besides the mature technology and cheap price, higher grid security of traditional prominent advantages, and its recent development in competition in a lot of new technology is closely related to such as 3d and double three-dimensional structure electrode and the sealed and tube type of new structure, and etc. Use new lead alloy electrode, can promote the gradual increase energy, cicyle life as 45 times. Lead-acid battery “and” one of the latest technology. Say so, not obsolete lead-acid batteries, a new technology lead-acid batteries.
What is the lead-acid battery “super”? So-called “super lead-acid batteries,” UltraBattery, supercapacitor and parallel lead-acid batteries can be called “the use of (for), and” within “and” evolution, is the ratio of electric power capacitor, long life to the advantage of lead-acid batteries, keep improving “, and “power, extend battery life, and the advantages of the circuit and enhance can simplify than energy, and decrease the total cost. It has great development in China is the electric bicycle and the electric car, will produce the huge economic efficiency and the social efficiency. Lead-acid battery “super” key technology has two, one is suitable for sulfuric acid electrolyte high-performance capacitance carbon materials, 2 it is to lead anode carbon capacitance of the composite.
In the new technology of lead-acid batteries, the energy can raise to more than 60-80wh/kg, power can improve to 600-700w, which is close to the technical index of lithium batteries.
863 plan should support the lead-acid battery technology development
Recently, the American President Obama announced that funding support us $2.4 billion project development the next generation of 48 battery and motor “production, including the arrangement of lead-acid batteries, respectively 3430 million dollars and $32.5 million support two companies develop lead-acid battery” project “. It is remarkable, the plan did not mention hydrogen battery and fuel cells.
For this YangYuSheng academician of the monk “exotic,” to chant “Buddha” touched on lead-acid batteries, no bias, should be a solid support a lead-acid batteries. Yang academician suggest that China should be clearly 863 plan lead-acid battery “support”, not hesitate. Therefore, he suggested that the government took 45 million RMB (about 1 in 10 U.S. support), 2, 3 production – research, plus 1 matching funds, enterprise with two years of lead-acid battery “developed” super and capacitance and form a certain scale, the production capability. This is coping with a financial crisis, one of the best move of stimulating domestic demand.
Lithium battery is the development direction of the future, but still waits for the enhancement
Yang academician think li-ion battery is a very good development direction, but at first to solve the security problem and qualified.
Lithium electricity safety has been for worry. 2009 handset lithium battery explosion in China, three seven times, technically, handset lithium battery relatively simple, not the problem, in parallel series. According to understand, handset lithium battery energy is probably 2wh, according to international statistics, probability of explosion is one thousand and one bus lithium battery energy is probably 20 million wh, if press watts hours and handset lithium battery, the probability of explosions could be 1%, it is the problem that nots allow to ignore. Lithium battery industry to solve problems, the battery safe future consequence is unimaginable. What is good, or security, an important industry professionals to attention is important.
The second is the rate of lithium batteries. Besides large capacity of lithium ion battery technology to improve, even further improve ZhengPinLv.
Most saving electric cars
The development of electric vehicle is the bottleneck, rather than simple concept of technology. In all kinds of electric cars, pure electric cars: one is the biggest advantage, 100 million cars with pure electric cars daily about alternative gasoline 1 million tons, 2 is pollution-free, All fees (3 + energy prices are less likely than fuel for cars, Four is simple structure, no oil and water, use, convenient maintenance, 5 is the battery can be in night cheap “electrical power lines and ready-made charging, sell the valley of” power “(mainly nuclear power and power grid” for peak “, and scattered saves storage hydropower construction.
China should great-leap-forward development priority, a charge can drive 150-200 kilometers of pure electric cars.
In addition, applied to various power battery electric vehicle development space, have to “the various battery, fair competition”.
Lead-acid batteries in the new energy storage areas in the competition scale advantages
China’s new energy development comes out, the academician Yang lead-acid batteries in scale, storage areas of competition advantages. In the new energy storage battery domain, its insiders have completed the lead-acid batteries used for long cycle life power storage system test. This system is connected with the overall power supply system, the peak load regulating operation. Test power storage system, three units respectively, and the most high 400kW 100kW 100kW and continuous operation, the two and a half years, battery voltage drop, increase the voltage difference problems, such as well. Confirm the lead-acid battery power storage system.
At the same time, the development of new energy storage battery must consider cost and life, stable performance and price of lead-acid batteries. China academy of military defense research and development center of chemical power has been accumulated military battery years, battery needs, overall research, technology development experience, pays special attention to the development of mass storage battery technology, especially the recommendation of lead-acid batteries in this field.
Lead-acid battery industry should notice to prevent lead pollution
People say that lead-acid batteries, often will lead pollution has said. Actually lead-acid battery is the highest in all cells and recovery of large enterprise production process has strictly control the lead. To solve the mining and smelting is lead the lead, batteries regeneration acid pollution, As long as the environmental protection department is responsible earnestly to implement environmental protection measures, enterprise value is not difficult to solve problems,.
Currently lead battery industry should strive to achieve from lead mining, batteries, old battery recycling operation, so can fully maximize reduce lead pollution. Why not pollute the environment of nuclear materials, nuclear power, because worried uranium from drilling to recycle and the whole process of environmental protection are doing very well. Lead-acid batteries can use nuclear power production chain of experience.
Another new lead-acid battery within the “super” lead than existing lead-acid battery is greatly reduced and the use of prolonging the workload and can reduce regeneration, these are conducive to alleviate the lead contamination directly.
Lead-acid battery production equipment to realize localization
Finally, the academician Yang spoke of lead-acid battery equipment problem. He said, now new lead-acid battery (for example, tubular cell) and old battery recycling business equipment many or import equipment. Expensive imported equipment, hamper the large-scale application. The battery enterprises in China imported production equipment, must consider as quickly as possible for the homemade equipment. Imported equipment is a very good opportunity, but also promote technological progress of China’s battery industry. Down the prices of the equipment, enterprise can adopt advanced don’t pollute equipment. Hope China lead-acid battery industry professionals working together, from drilling to old battery in the whole process of early recovery plan to promote, relevant equipment.
