METHOD FOR MANUFACTURING LCO@OXIDE@CNT MULTICOMPOSITE CATHODE MATERIAL

A method for manufacturing a LCO@oxide@CNT multicomposite cathode material comprises the following step of: mixing a LLZO material and a plurality of large LCO (LiCoO) particles to form a plurality of composite LCO particles, wherein the LLZO material is formed by a LLZO (LiLaZrO) or a LLZO doped with at least one metal. The LLZO material includes a plurality of large LLZO particles and small LLZO particles. Then an oxygen assisted sintering is performed on the composite LCO particles to form a plurality of sintered powders. A first LLZO interphase layer is formed between each large LLZO particle and the respective large LCO particle. A second LLZO interphase layer is formed between each small LLZO particle and the respective large LCO particle. Then the sintered powders are mixed with a plurality of first carbon nanotubes.
