锂电池正极材料CuFeS2的电化学性能研究

Abstract In this paper CuFeS2 powder prepared by hydrothermal method is taken as cathode materials of lithium battery assemblybattery for electrochemical performance test. The result shows that the battery in the current density is C/50 a discharge capacity of 20益reached 1100mAh/g 80益discharge capacity reached 1850mAh/g. When current density was C/2 the discharge capacity is 510mAh/g. -20益discharge capacity can reach 475mAh/g. In addition the battery discharge mechanism is also discussed.院锂电池 CuFeS2 正极材料 电化学性能Key words lithium battery CuFeS2 cathode material electrochemical performance中图分类号院TM911 文献标识码院A 文章编号院1006-4311（2014）15-0312-020
