Synthesis by sol–gel process and characterization of LiCoO2 cathode materials

The cathode material LiCoO2 is synthesized by a sol–gel process. The structure and electrochemical properties are studied by DTA–TG, XRD, SEM, and electrochemical measurements. It is found that a homogeneous LiCoO2 powder with purity and high electrochemical intercalation capacity can be obtained by the sol–gel process.
