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 L i( Alx Co1- x) O2 的充放电特性 ,并与相同条件下制备的传统材料 L i Co O2 进行对比 .结果表明 ,70 0℃烧结的Li( Al0 .3 Co0 .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 Li Co O2 .
The charge-discharge characters of a new cathode material with a high energy storage density, Li(Al xCo 1-x)O 2, were investigated and compared with those of the traditional cathode material, LiCoO 2, which was prepared under the same conditions. The results show that Li(Al xCo 1-x)O 2 sintered at 700 ℃ has a higher charge-discharge flat potential plateau, and a higher capacity than LiCoO 2 has under the same conditions.
