Abstract

Nanometric-sized LiNi_0.8Co_0.2O₂ powders were obtained from the resins synthesized by the polymerization of citric acid and cellulose. The powder calcined at 600degC exhibited a pure high temperature phase of LiNi_0.8Co_0.2O₂. The surface response method was applied for the optimal preparatory conditions of LiNi_0.8Co_0.2O₂ powder; as a result nanometric-sized LiNi_0.8Co_0.2O₂ powder with average particle size of about 65 nm was prepared. The first run discharge capacity of the electrode prepared by the optimal experiment was 168 mAh/g.Key words: LiNi_0.8Co_0.2O₂, nanometric-sized, optimal preparatory conditions.
