  • Positive electrode materials for lithium ion batteries and process for preparing the same
    Patent number: 9484577
    Abstract: Provided are a positive electrode material for lithium ion batteries and a process for preparing the same. The positive electrode material for lithium ion batteries comprises a composite positive electrode material consists of LiCoO2 and an auxiliary positive electrode material, the general formula of the auxiliary positive electrode material is LiCo1-x-yNixMnyO2, wherein 0<x<0.9, 0<y<0.9, 0<x+y<0.9, and the LiCoO2 is a modified LiCoO2 coated with an Al2O3 film. The overcharge performance of the batteries can be significantly increased and the use amount of the overcharge additive can be reduced by using the positive electrode material so as to its improve the cycle performance of the batteries and improve the anti-overcharge safety in the special applications and the charging conditions.
