An "all-climate lithium battery" that can work stably at minus 40°C and minus 60°C has been successfully developed by Xinjiang researchers recently. This technology is expected to solve the problem of low temperature inability to charge lithium batteries commonly encountered in energy storage, especially for The northern regions with cold winters like Xinjiang are of great significance.

　　An "all-climate lithium battery" that can work stably at minus 40°C and minus 60°C has been successfully developed by Xinjiang researchers recently. This technology is expected to solve the problem of low temperature inability to charge lithium batteries commonly encountered in energy storage, especially for The northern regions with cold winters like Xinjiang are of great significance.　　 In the "Maker China" Xinjiang Innovation and Entrepreneurship Competition Urumqi Division Trial held on August 29, the "All Climate Lithium Battery" stood out from many outstanding projects and won the first prize in the Urumqi Division Maker Group.

　　This technology was developed by a local company, Xinjiang Zhongneng New Power New Energy Technology Co., Ltd., which was established in June this year. The core technology was developed by Dr. Wang Lei from the Xinjiang Institute of Physics and Chemistry, and has completed various high and low temperature conditions. The following product testing work is about to enter the stage of commercial product production.

　　The reporter learned that lithium batteries are currently an electrochemical energy storage and power device commonly used in electric vehicles. Compared with other batteries, they have the advantages of high energy density and long cycle life. However, its low temperature performance is extremely poor. The mileage of electric vehicles in cold weather is reduced by 40%-50%, and they cannot be charged below zero, making electric vehicles a "flower in a greenhouse."

　　In order to solve the low-temperature problem of lithium batteries, various technologies have been developed by the industry and academia, but the existing solutions are usually complicated and costly, or their performance at room temperature and high temperature is impaired. Therefore, the development of a low-cost, all-climate, high-efficiency lithium-ion battery plays an important role in the development of the electric vehicle industry.

　　"Although the company has not been established for a long time, it has been focusing on the development of high and low temperature resistant lithium ion batteries and energy storage systems and the research and development of solutions. By providing high and low temperature resistant lithium ion battery positive and negative materials, it can be used for electric vehicles and unmanned Companies such as machines and robots provide solutions for use in high and low temperature environments." Huang Chao, the company’s deputy general manager, said that "all-climate lithium batteries" related products are widely used in energy, information, transportation, national defense, aerospace and other industries. , Has broad market prospects.

　　Fu Ming, a judge in the Urumqi Division and a doctor of Dongxing Securities Co., Ltd. Xinjiang Branch, believes that the country is currently vigorously developing new energy vehicles and lithium-ion battery energy storage technology. There are also many strong domestic companies studying lithium batteries. Xinjiang Zhongneng New Power New Energy Technology Co., Ltd.'s "all-climate lithium battery" is unique in low-temperature applications, has intellectual property rights, and is in the forefront of the industry. This technology has broad application prospects in alpine regions such as Xinjiang, Northeast China, and even Central Asia, Russia and other regions. Therefore, the panel of judges gave a high evaluation of the project and hoped to achieve good results again in the Autonomous Region Innovation and Entrepreneurship Competition held in September.
