Y(Ⅲ)和Co(Ⅱ)复合掺杂非晶态Ni(OH)2材料的电化学性能
Electrochemical Performance of Y ( Ⅲ ) and Co ( Ⅱ ) Codoped Amorphous Nickel Hydroxide as Electrode Active Material
摘要
Abstract
Amorphous nickel hydroxide codoped with Y(Ⅲ ) and Co( Ⅱ ) is synthesized by micro-emulsion method. The microstructure and composition of the samples are characterized by XRD, SAED, SEM, EDS and Raman. Electrochemical properties are investigated when sample power codoped with Y ( Ⅲ) and Co ( Ⅱ ) is made as nickel electrode active material, then the MH-Ni battery assembled. The results show that the sample doped with Y( Ⅲ) and Co( Ⅱ ) is amorphous Ni( OH)2 with large amount of defects. Electrode made of the sample shows low charge-transfer resistance and strong conductivity. The specific capacity is 355. 7 mAh/g and discharged plateau potential is 1. 278 V when the charging current, discharging current and end potential are 80 mAh/g ,40 mAh/g and 1.0 V respectively.关键词
