英文摘要	采用络合法制备了锂离子电池的活性正极材料LiNi0.8Co0.2O2粉体,该合成材料结晶良好,层状结构发育完善.电池充放电测试表明,作为锂离子电池正极,其电化学性能与LiNi0.8Co0.2O2粉体的合成温度有关,其中以900℃下合成得到的材料性能最优:第1次放电比容量高达142mAh/g,循环30次后可逆比容量仍高达122mAh/g,容量损失为14.5%.文中对容量退化的原因进行了分析.; 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.; 作者联系地址：中国科学院上海硅酸盐研究所功能陶瓷工程与研究中心,中国科学院上海硅酸盐研究所功能陶瓷工程与研究中心,中国科学院上海硅酸盐研究所功能陶瓷工程与研究中心,中国科学院上海硅酸盐研究所功能陶瓷工程与研究中心,中国科学院上海硅酸盐研究所功能陶瓷工程与研究中心上海200050 ,上海200050 ,上海200050 ,上海200050 ,上海200050; Author's Address: Center of Functional Ceramic Research and Engineering, Shanghai Institute of Ceramics, Chinese Academy of Sciences, Shanghai 200050, China
