| Abstract: |
| Ternary precursor was synthesized applying sulfuric acid leached solution of waste capacitive type NI-MH power battery as raw materials through purification, adjusting ion concentration of Ni, Co and Mn, coprecipitation with ammonium hydroxide and sodium carbonate. The precursors are of layered spherical structure with uniform particle size and normal distribution. Ternary cathode material prepared by coprecipitation was assembled into a soft packing battery. This cathode material exhibits discharge capacity of 160 mAh/g above under discharging rate of 0.2C, 0.5C, and 1.0C. |
