Received Date: 27 August 2002

A novel gel-like process has been developed for synthesizing Li_aNi_0.8Co_0.2O₂ powders, using citric acid as a chelating agent. This process improves the homogeneity of constituent cation and enhances their reactivity in the obtained precursor. The results of electrochemical test demonstrated that these materials exhibited excellent electrochemical properties. Its initial capacity reached 181.6 mAh/g and reversible efficiency at the first cycle is about 88.6%.
