Recently, the research team led by Chen Jian, researcher at Dalian Institute of Chemical Physics, Chinese Academy of Sciences, made new progress in lithium-sulfur secondary battery technology research and development.After the third-party authority test, the newly developed energy-type lithium-sulfur secondary battery to achieve 609Wh / kg, refreshing the recording of the specific energy of the secondary battery.The battery also shows excellent environmental adaptability: the discharge specific energy reaches 400Wh / kg in the environment of -20 ° C; in the arctic environment at -60 ° C, Can still work, showed significantly better than the low-temperature performance of lithium-ion battery.In addition, the newly developed power lithium-sulfur rechargeable batteries with a sustained discharge rate greater than 4C, pulse up to 10C. At present, the battery has been developed by The third party safety performance test using the national military standard, safety and meet the requirements of use.The study proved its potential in the field of electric vehicles, but in the realization of its practical application, the need to further overcome the bottleneck of poor battery cycle performance .
Zhongke Paisi Energy Storage Technology Co., Ltd. is a joint venture of Dalian Chemical Industry Co., Ltd., which has industrialized lithium-sulfur battery technology. Now it has built 6,700-level modern lithium-sulfur battery production workshop and automatic production line with a capacity of 3 million Ah / year and is the first The company specializing in the production and sale of lithium-sulfur batteries is also the nano-pilot industrial lithium-sulfur battery base of the Chinese Academy of Sciences. In recent years, the team has made great strides in the industrialization of lithium-sulfur batteries The jointly developed lithium-sulfur battery for solar drone participated in the system-wide ground test of the overall unit organization, which achieved good results and passed user acceptance.
