Research progress of all-solid-state lithium batteries and key materials, lithium ion battery ProcessorXinjiang related companies have made progress in the research of low-temperature-resistant lithium battery cathode materials

　　The composite material shows superior low-temperature performance and rate performance: at -20°C, it maintains a reversible capacity of 127.7mAh/g, which is much better than the 86.4mAh/g capacity of nickel cobalt manganate material, and is excellent The highest capacity (106 mAh/g) of the modified lithium nickel cobalt manganese oxide material is reported so far; at a high current density of 1C, after 100 cycles, it maintains a capacity of 141.7 mAh/g.

　　Lithium nickel cobalt manganese oxide (LiNi1/3Co1/3Mn1/3O2) ternary cathode material has attracted wide attention of researchers since its discovery. At present, nickel cobalt manganese oxide lithium cathode material has been widely used and researched, but its performance at low temperature and rate performance is not satisfactory. It can almost only work in room temperature environment, which cannot meet the conditions of extreme temperature and rapid charging and discharging of batteries. The needs of the job. In view of this, scientific research institutions around the world are actively exploring new materials and new methods to improve the performance of lithium-ion batteries under extreme conditions.
