| Abstract: | Cathode material nickel sulfide(NiS)was prepared by hydrothermal and mechanical alloying routes,respectively. The structure,morphology and electrochemical performance of the materials were analyzed by SEM,XRD,cyclic voltammetry and charge-discharge methods. The material prepared by hydrothermal route had uniform particles and a high degree of dispersion. When charge-discharge at 1.0～3.0 V with the current density of 0.1 mA/cm~2,its initial specific discharge capacity was 584.6 mAh/g. |
