| Abstract: | To improve the electrochemical performance of spherical Ni(OH)2,cobalt coated spherical Ni(OH)2 was obtained by spraying cobalt saline solution,through oven drying and alkalization processes.XRD and powder micro electrode cyclic voltammetry simulated charge-discharge tests were taken on it and sample battery was made for the testing.The material coated with 3.0% cobalt had fine conductivity,the tap density was 2.05 g/ml,the 1 C and 10 C discharge specific capacity of electrode prepared was 260 mAh/g and 228 mAh/g,respectively. |
