【Abstract】 LiCoO₂ cathode materials were synthesized with Li₂CO₃ and different Co₃O₄ as raw materials,in which Co₃O₄ was prepared by various processes.XRD test showed that the values of the lattice parameters a and c of LiCoO₂ prepared with different Co₃O₄ as raw materials were different.The electrochemical performance tests indicated that LiCoO₂ synthesized by Co₃O₄ with bigger specific surface area,and the one synthesized by Co₃O₄ with bigger dimension of micro crystal,had higher initial discharge specific capacity and better cycling stability,respectively.更多还原
