1. In our daily life, lithium batteries are indispensable. Do you know that there are many kinds of cathode materials for lithium batteries? Now Tuopai will explain to you that there are actually five kinds of cathode materials: lithium cobalate, lithium manganate, lithium nickel cobalt manganate, lithium iron phosphate and lithium nickel cobalt aluminate. The ternary cathode materials of lithium ion batteries account for a large proportion. The purpose of ternary cathode materials for lithium ion batteries is to reduce material cost, 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 cycling performance and thermal stability, and the prices of manganese and nickel are lower than cobalt, the material cost can be greatly reduced. It is an ideal cathode material for lithium ion batteries.

2. Nickel cobalt manganese ternary material, a small amount of lithium nickel oxide mixed lithium cobalt oxide mixed lithium manganate. Compared with lithium niobate, the energy density of ternary materials is lower, but the stability is greatly improved. Compared with lithium cobalt oxide, ternary materials have a lower platform and a lower maturity, but their safety and recoverability, especially the feasibility of high charging voltage, are higher. Compared with lithium manganate, the safety of ternary system is much lower, but it has great advantages in high temperature performance and energy density. At present, ternary system is widely used in China as a partial substitute for lithium cobalate. Medium and low-end consumer electronic products are mixed with lithium manganate or lithium cobalate, and medium and low-end power markets are mixed with lithium manganate.

3. What are the advantages of ternary cathode materials for lithium ion batteries? Ternary materials are considered to be the first choice of lithium-ion batteries because of their low price and stable performance, and lithium-ion batteries with ternary materials as cathode have many advantages. (1) The ternary cathode materials for lithium ion batteries are inexpensive and low in cost. (2) The cycle performance is better than that of ordinary lithium cobalate. (3) The capacity per gram is slightly higher than lithium cobalate. (4) Relatively balanced capacity and security
