The difference between lithium battery 523 and 622 is:
1. 622 indicates that the positive electrode material of this model lithium battery is LiNiCoMnO2, the negative electrode material is graphite, and the electrolyte is EC/. DMC (1/1).
2. 523 represents the positive electrode material of this model lithium battery is LiCoO2, the negative electrode material is graphite, and the electrolyte is EC/DMC (1/1). The main difference between these two types of lithium batteries is their different cathode materials. The ternary lithium battery of Model 622 considers both energy density and power density, while the ternary lithium battery of Model 523 is superior in terms of power density. Ternary lithium battery means that the cathode material of the lithium ion battery is ternary cathode material and its general formula is LiMO2 (M = Ni, Co, Mn). LThe numbers refer to the ratio of the elements Ni, Co and Mn, such as the full chemical formula of NCM811 LiNi0.8Co0.1Mn0.1O2. The Ni content in the ternary material is positively correlated with the capacity and energy density of the cathode material, the higher the Ni content, the higher the capacity and energy density of the battery. Therefore, 811 has the highest energy density among 523, 622 and 811. However, due to the reduced content of Co and Mn, its motor performance and safety are reduced.
Both are lithium-ion rechargeable batteries, but the difference lies in the different standards of raw materials, production processes and working platforms.
