| Abstract: | Co doped amorphous nickel hydroxide powder is prepared by the method of micro-emulsion.The phase structure of the sample is analyzed.Charge and discharge performances,cyclic volt-ampere characteristics of the adulterated electrodes are tested.The effect and corresponding mechanism of the charge and discharge performances of some factors are studied.Cyclic voltammeter characteristics of the adulterated electrodes are tested.The results show that the structure of the sample stability and reversibility are satisfactory.The discharge specific capacity can reach 317.75 mAh/g when charged at 100 mA/g for 4 h and discharged at 50 mA/g to 1.0 V,with smooth discharge voltage at 1.240 V showing a high electrochemical activity. |
