Abstract

The layered LiNi0.8Co0.2O2 compound, which has been of great interest for lithium ion batteries, was prepared at low temperatures by calcining a complex precursor at different temperatures. The physical properties of the synthesized cathode materials were discussed in the light of structural (XRD). The charge and discharge cycling of the cells containing the synthesized oxide as the positive electrode in conjunction with lithium metals and employing a non_aqueous electrolyte showed that LiNi0.8Co0.2O2 treated at 900 ℃ exhibited excellent performances. The first discharge capacity of LiNi0.8Co0.2O2 is 142 mAh/g and its capacity loss is 8%. The mechanisms of capacity degradation are discussed based on phase and microstructure analyses.
