What are the characteristics of the Ru0026D and production of power lithium batteries?

During the 12th Five-Year Plan period, my country's new energy vehicles have made great progress. At the beginning of the 13th Five-Year Plan, new energy vehicles have attracted attention from all walks of life. So, as the core lifeblood of new energy vehicles, what are the characteristics of the research and development and production of power lithium batteries in my country? Recently, a reporter from my country's public transport network interviewed the new energy vehicle major project expert group of the Ministry of Science and Technology on the application of domestic new energy vehicle power lithium batteries. Team leader Wang Binggang. Wang Binggang believes that my country has made great progress in new energy vehicle technology, especially battery technology. In the beginning, my country also made foreign products such as nickel-metal hydride batteries and lithium-ion batteries, which had poor lifespan and were very expensive. Now, the lithium iron phosphate battery has reached a mature stage, and the safety and stability are relatively good, and the lithium iron phosphate battery has a foothold. The use of ternary batteries is also very fast. At present, new energy vehicles are developing rapidly, but there are also many problems, especially the safety and attenuation of power lithium batteries. The promotion of new energy vehicles is now very fast, the basic supply is insufficient, and the battery car battery factory is in the queue. This will lead to a bad phenomenon. Individual companies are one-sided pursuit of the number, or some units are eager to get bonuses and get rich quickly, no matter what. The battery can be loaded in quality, causing some accidents and premature deterioration or battery. If the battery declines severely, consumers will be unwilling to file a claim, and the number is not one or two, who will pay for the battery? If the bus company, due to the battery decline, it may also affect normal operation. These are all foreseeable problems. Wang Binggang told the reporter of my country Passenger Car Network: I have already said, don't rush to use three-material batteries on buses. My core idea is that there should be no accidents on buses. I am worried that some companies do not guarantee the quality of the battery, and there will be more problems with three batteries. But I do not advocate simply saying what materials are available and what is not. In fact, if the lithium iron phosphate battery is not manufactured well, it will catch fire. Therefore, we should focus on formulating strict requirements and regulatory measures for passenger car battery products. What should be done specifically? First of all, we now have clear safety regulations for monomers, and no clear safety assessment indicators for modules and battery systems. The second is to implement strict monitoring of new energy buses, and clarify the content and responsibilities of monitoring. For this reason, Wang Binggang has repeatedly called on people in the industry to remain vigilant and be prepared. He said that the most important thing is that we should adhere to the battery quality standards. Second, national policies and the entire industry must be prepared. After one or two years, if the battery has a serious premature decline, there should be a way to compensate consumers. If not handled properly, this issue will impact the entire promotion of new energy vehicles. The development of power lithium batteries is not only fast. Recently, a seminar on 'Interpretation and Trends of New Energy Policies for Urban Public Transport' co-sponsored by the my country Electric Vehicle Association 100 and the Institute of Highway Science of the Ministry of Transport was held in Beijing. Director of the State Key Laboratory of Automotive Safety and Energy, cming-gao Ouyang of my country's Electric Vehicles, Executive Deputy Director Conference my country Litigation Reporter pointed out that since 2014, my country's electric battery industry has developed rapidly and investment has risen, but for safety reasons, The development of power lithium batteries in our country should not be blindly and slowly. Ouyang Minggao pointed out that starting from the 15th year, my country has begun to carry out large-scale research and development of new energy vehicles. Through the 15th Five-Year Plan, the 11th Five-Year Plan and the establishment of key projects in the 12th Five-Year Plan, my country's new energy vehicles have entered the industrialization stage from the demonstration and evaluation stage. Since 2014, the Chinese government has issued a series of preferential policies. my country's new energy automobile industry has entered a period of rapid development, battery investment is rising rapidly, and the battery industry is rising rapidly, but there is still a problem of insufficient supply. Ouyang Minggao pointed out that the development of the battery industry is not only a matter of investment, but investment in research and development is more important. For the power system of electric vehicles, whether it is an extended range plug-in hybrid power system, a pure electric system or a fuel-powered battery power system, we should comprehensively consider and analyze the core technology and advantages and disadvantages of each system to make stable improvements and increments. Development. Therefore, the development of power lithium batteries in China should maintain a reasonable development speed. To achieve an integrated platform for urban public transport power systems, it is necessary to strengthen and deepen industrial development, improve scientific research and technical capabilities, and ensure the safe, stable and rapid development of new energy vehicle development projects.
