摘要: 研究应用于锂二次电池阴极的新型高能量密度存贮材料 Li(AlxCo1-x)O2的充放电特性, 并与相同 条件下制备的传统材料LiCoO2进行对比. 结果表明, 700 ℃烧结的Li(Al 0.3Co0.7)O2有较好的 充放电平台, 电化学容量大于同样条件下制备的LiCoO2.

关键词: 锂二次电池, 阴极材料, Li(AlxCo1-x)O2, 充放电特性

Abstract: The charge-discharge characters of a new cathode mater ial with a high energy storage density, Li(AlxCo1-x )O2, were i nvestigated and compared with those of the traditional cathode material, LiCoO2, which was prepared under the same conditions. The results show th at Li(AlxCo1-x)O2 sintered at 700 ℃ h as a higher charge-discharge flat p otential plateau, and a higher capacity than LiCoO2 has under the same conditions.

Key words: rechargeable lithium batteries, cathode materials, Li(AlxCo1-x)O2, charge-discharge ch aracter
