| Abstract: |
| LiCoxMn2-xO4 cathode material was synthesized by liquid phase reaction and high temperature ball milling sintering method. The effect of doping amounts of cobalt on crystal structure, surface morphology and electrochemical properties of materials were studied. The results show that the initial discharge capacity of the material drops with the increase of cobalt doping amounts, and cycling performance of the material is greatly improved. Initial discharge capacity of LiCo0.05Mn1.95O4 is 119.0 mAh/g, and the capacity retention rate after 100 cycles is 92.52% at various rates, which exhibits an excellent electrochemical reversibility and cycling stability performance. |
