Do you know the important advantages of ternary cathode materials for lithium batteries?

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 lithium cobaltate mixed 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. It is mixed with lithium manganate or lithium cobaltate for low-end consumer electronics, and mixed with lithium manganate for low-end power market. Ternary materials are known as the material of choice for lithium batteries because of their low price and stable performance. Lithium batteries with ternary materials as the positive electrode have many advantages. 1. Lithium battery ternary cathode material is inexpensive and low in cost 2. Cycle performance is better than normal lithium cobalt oxide 3. Gram capacity is slightly higher than lithium cobalt oxide 4. Capacity and safety are more balanced 5. Good overcharge resistance , Easy to synthesize 6. When charging and discharging with high current, the polarization is small. The battery can be charged continuously at 3C and high input and output capacity at 5C. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
