摘要
Abstract
Li1.2Ni0.13-x/3Co0.13-x/3Mn0.54-x/3CrxO2 (x=0,0.01,0.02,0.03) cathode materials were prepared by high temperature solid state method with the characters of uniform particle size distribution,high crystallization degree and excellent structural stability.Li1.3Ni0.13-x/3Co0.13-x/3Mn0.54-x/3CrxO2 (x=0.02) was discharged at 0.1 C,0.2 C,0.5 C,1 C and 2 C with specific capacity of 332.11,308.86,271.06,191.56,113.92 mAh/g.After 50th cycles at 0.1 C,the capacity retention is 97％.Therefore,Li1.2i0.13Co0.13Mn0.54O2 doped Cr shows better cycling stability,rate performance and cyclic stability.关键词
