Lithium battery technological innovation is accelerating new energy vehicles into mainstream choices

On the 12th, the 15th International Forum on Power Lithium Battery Technology and Industrial Development hosted by Tsinghua University, Institute of Physics, Chinese Academy of Sciences, and Shunyi District People’s Government was held in Shunyi. Topics such as ideas and evaluation standards are cut into, and the development of lithium battery industry technology is analyzed and explored in an all-round way. With the rapid development of the new energy automobile industry, battery life, low-temperature performance, and battery life have become people's most concerned issues. Solving the contradiction between the high energy density and safety of lithium batteries, reducing the cost of lithium batteries, breaking through the material technology bottleneck, and improving the recycling and reuse management system have become important challenges facing the development of the industry, and improve the safety of lithium batteries for vehicle power , Life, low temperature characteristics and cost reduction have become the direction of industrial technology development. Wu Feng, an academician of the Chinese Academy of Engineering, believes that the energy density of lithium batteries now exceeds 250 watt-hours per kilogram and can be reused up to 2,000 times under the requirement of ensuring safety and meeting national standards. 'It can be said that the overall performance has gone up several steps.' Wu Feng believes that the current market for new energy vehicles is huge. As the heart of new energy vehicles, the development of power batteries is crucial. In the future, power batteries will achieve a comprehensive and balanced development in terms of energy density, safety, service life, and cost, and become the mainstream choice in the market. According to reports, my country's lithium battery industry is developing rapidly. With the key support of national science and technology projects, China's lithium battery industry has made great progress in the research of key technologies, key materials and products in the field of power batteries. According to the data, Beijing's pure electric vehicles have entered the marketization stage, the product structure has been optimized and upgraded, and a relatively complete industrial chain has been established. As of July, Beijing has promoted 350,000 pure electric vehicles and built more than 200,000 charging facilities.
