What are the fundamental advantages of ternary cathode materials for lithium-ion batteries?

There are five types of positive electrode materials: lithium cobalt oxide, lithium manganate, lithium manganese nickel cobalt manganese, lithium iron phosphate, lithium nickel cobalt aluminate, and the ternary positive electrode materials of lithium-ion batteries account for a large proportion. The ternary cathode material for lithium-ion batteries is used to reduce material cost, improve material safety and layout invariance. However, excessive manganese content will crush the layered layout of the material and reduce the specific capacity of the material. Because LiNi1/3Co1/3Mn1/3O2 has high specific capacity, good recycle performance, good thermal stability, and the value of manganese and nickel is lower than that of cobalt, it can greatly reduce the cost of materials. It is an ideal lithium-ion battery cathode material. The ternary material of nickel, cobalt and manganese is a bit like lithium nickelate mixed with lithium cobaltate mixed with lithium manganate. Compared with lithium nickelate, the energy density of the ternary material is lacking, but the invariance 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 reincarnation, especially the feasibility of high charging voltage, are higher. Compared with lithium manganate, the security of the three-year old is much lower, but the high-temperature performance and energy density have great advantages. At present, the domestic ternary is generally used in the sector to replace lithium cobalt oxide. It can be mixed with lithium manganate or lithium cobalt for low-end consumer electronics, and mixed with lithium manganate for low-end power market. What are the advantages of ternary cathode materials for lithium-ion batteries? Because of their low value and unchanged performance, ternary materials are known as the preferred materials for lithium-ion batteries, and lithium-ion batteries that use ternary materials as the positive electrode have many advantages. Kind of advantage. 1. The ternary cathode material of lithium-ion battery is not expensive and the cost is low. 2. The cycle performance is better than normal lithium cobalt oxide. 3. The gram capacity is slightly higher than that of lithium cobalt oxide. 4. The capacity and security are balanced. 5. Overcharge resistance Good and easy to synthesize 6. When charging and discharging with high current, the polarization is small. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
