Abstract:A new lithium ion battery cathode material, composite oxide LiNiyCozMn1-y-zO2, was synthesized. The structure and physical properties of the material, including composition, distribution of size, density and specific surface area, were discussed. The characteristic of charge and discharge, reversible specific capacity and cycle property were also studied. The relationship between the structure and properties of the composite oxides was explored. The results show that the composite oxide with a reasonable composition is beneficial to the improvement and enhancement of the properties.
Key words: lithium ion; batteries; cathodic material; LiNiyMn1-y-zO2; LiNiO2
