摘要：

A convenient, economical strategy of the "dipping-grinding-sliming"process followed by solid phase sintering was used for surface modification of Li-rich layered cathode materials Li1.2Mn0.54Ni0.13Co0.13O2. The experimental results expressed that compared with pristine material, the surface-modified cathode material exhibited satisfactory cyclic stability. It had an initial capacity of more than 280 mAh center dot g(-1). After 70 charging-discharging cycles at 0.5C, it had capacity retention of 91.6%.
