Lithium cobalt oxide (LiCoO 2 ) has received considerable attention in the last few years and is a well-known cathode material for high voltage (4 V) rechargeable Li-ion batteries. A simple chemical approach based on aqueous solution chemistry has been developed to synthesize molecularly mixed amorphous precursors. The precursors begin to transform to form LiCoO 2 upon heat treatment...
The cathode material LiCoO 2 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 LiCoO 2 powder with purity and high electrochemical intercalation capacity can be obtained by the sol-gel process.
