LITHIUM COBALT SPINEL OXIDE: A STRUCTURAL AND ELECTROCHEMICAL STUDY

Lithium cobaltite, LiCo(2)0(4), prepared by thermal decomposition of nitrates salts was synthesized at 400 °C. X-ray Rietveld refinement showed the presence of two phases: a cubic spinel (Co(3)0(4)) and other corresponding to spinel-like, which could not be classified as LiCo(2)0(4) or LiCo0(2) sinc...
