What is a ternary cathode material for lithium batteries

There are five types of cathode materials: lithium cobalt oxide, lithium manganese oxide, lithium manganese nickel cobalt manganese, lithium iron phosphate, lithium nickel cobalt aluminate, and lithium battery ternary cathode materials occupy a large proportion. Ternary cathode materials for lithium batteries are used to reduce material costs, improve material safety and structural stability. However, excessive manganese content will destroy the layered structure of the material and reduce the specific capacity of the material. Because LiNi1/3Co1/3Mn1/3O2 has high specific capacity, good cycle performance, and good thermal stability, and the prices of manganese and nickel are lower than cobalt, it can greatly reduce the cost of materials and is an ideal cathode material for lithium batteries. Nickel-cobalt-manganese ternary material is a bit of lithium nickelate mixed with lithium cobaltate mixed with lithium manganate. Compared with lithium nickelate, the energy density of ternary materials is lacking, but the stability is greatly improved. Compared with lithium cobalt oxide, the platform of the ternary material is slightly lower, and the maturity of the material is somewhat different, but the safety and cyclability, especially the feasibility of high charging voltage, are higher. Compared with lithium manganate, the safety of Sanyuancai Lao is much lower, but it has great advantages in high temperature performance and energy density. At present, the domestic ternary is generally used as a partial replacement for lithium cobalt oxide, mixed with lithium manganate or lithium cobalt oxide for low-end consumer electronics, and mixed with lithium manganate for low-end power market.
