Alumina can be modified during the synthesis of electrode materials, improving their cycling properties and safety.
Coating alumina material on the surface of the cathode material can avoid direct contact between the active cathode material and the electrolyte, reduce the loss of electrochemical specific capacity, reduce the side reaction and heat generation in the battery cycle process, improve the electrochemical characteristics of the cathode material, improve its cycling performance, and strengthen the structural stability of the material.
There are three types of alumina products for material coating: ZKC432, ZKC440A and ZK540A.
