英文摘要	Electrochemical properties of LiNi1/3Mn1/3Co 1/3O2 powders have been investigated for a sample free on any impurity and cation mixing reduced to 1.3%. The discharge capacity decreases from 174 mAh/g (0.01C) to 133 mAh/g when cycled at a high current density of 3C-rate. The sample reaches high capacity of 146 mAh/g after 90 cycles when using 1C-rate for discharging, with high capacity retention of 97%. The diffusion coefficient of the Li+ ions has been determined as a function of the delithiation rate by GIT and EIS analysis. The diffusion coefficient is in the range 1011-1012 cm2/s, and goes through a maximum at intermediate delithiation rate. ?The Electrochemical Society.; EI; 0
