What are the cathode materials of energy storage lithium batteries?

1. Based on traditional cathode materials (LiCoO2, LiMn2O4, LiFePO4, etc.), develop related various derivative materials, through doping, coating, adjusting microstructure, controlling material morphology and size distribution , specific surface area, impurity content and other technical means to comprehensively improve its specific capacity, rate, cycleability, compacted density, electrochemistry, chemical and thermal stability.

2. Ternary materials (LiNixCoyMn1-x-y) and lithium-rich materials (Mn-based and V-based) have large development and technical research space and broad application prospects.

3. A series of transition metal fluorides, oxides, sulfides and nitrides have been proven to be able to achieve multi-electron transfer and achieve high capacities.

4. It is mainly divided into conductive polymers, sulfur-containing compounds, nitrogen-oxygen free radical compounds and carbonyl compounds, etc.
