802540 polymer battery.What are the current technological breakthroughs in the automotive battery field?

　　Under the dual pressure of energy crisis and low-carbon environmental protection, countries around the world are actively developing new energy vehicles. New energy vehicle brands from Japan, the United States and Germany have already occupied a certain market share. New energy vehicles have always been the mainstream trend in the future, and internal combustion engines will gradually be replaced by electric motors. Battery technology has always been a key factor restricting the development of electric vehicles. It is the source of power for the entire vehicle and will directly affect the cruising range of electric vehicles and even the quality and cost of the entire vehicle. It is reported that China has made major breakthroughs in battery technology. Solid-state batteries have achieved mass production. It is no longer a dream for electric vehicles to have a cruising range of more than 1,000km. The emergence of this technology can be said to be a timely help. China has been making every effort to develop electric vehicle technology, but battery power issues have become an obstacle. Now, the electric vehicle market is finally seeing a glimmer of hope. This new technology was jointly developed by Nan Cewen, an academician of the Chinese Academy of Sciences, and a doctoral graduate from Tsinghua University. Production has now begun, and the annual output is expected to reach 0.1GWh solid-state batteries, with an energy density exceeding 400Wh/kg. Why is this new technology a major breakthrough? You know, even if Tesla is a leader in the field of new energy vehicles, the current maximum range can only reach 600 kilometers. This means that if this new technology is applied to new energy vehicles, the cruising range of electric vehicles can be greatly increased. Moreover, compared with liquid batteries, solid-state batteries have the advantages of high safety, low cost, high energy density and power density, and long service life. Additionally, solid-state batteries are easy to recycle. In fact, the battery production management and recycling system can solve the problem of battery pollution, which is of great significance to the realization of truly pollution-free electric vehicles. At present, the focus of research at home and abroad is battery technology. As one of the key technologies of electric vehicles, battery technology has always been a bottleneck in the development of electric vehicles. The capacity, volume, weight, lifespan and price of the battery will be directly related to various factors such as the battery life, safety and selling price of electric vehicles. Countries are competing with each other to take the lead in this research, and solving the battery problem is of great significance to the popularization of electric vehicles.
