【 摘 要 】

The structure and electrochemical properties of the Li_xCo_yNi_1-yO₂ (y=0.1, 0.3, 0.5, 0.7, 1.0) system synthesized by solid state reaction with various starting materials have been investigated to optimize the characteristics and synthetic conditions of the Li_xCo_yNi_1-yO₂. The first discharge capacities of Li_xCo_yNi_1-yO₂ are 60 mAh/g-180 mAh/g with synthetic conditions. Among them, the Li_xNi_0.7Co_0.3O₂, which was prepared with LiOH, NiO, and Co₃O₄ at 850�?, had the best electrochemical properties. The first discharge capacity of the compound was 180 mAh/g.
