摘要/Abstract

摘要： 采用水合联氨或次亚磷酸氢钠作还原剂，分别在酒石酸钾钠和氨的配合体系中镀覆球形氢氧化镍，对一定金属钴镀覆量下的产物进行了XRD和SEM分析与观测. 制成的粘结式电极的1 C倍率大电流放电容量测量结果表明，镀覆钴可提高放电容量11%~32%.

关键词: 氢氧化镍, 化学镀钴, 1 C倍率放电容量

Abstract: Cobalt was deposited on spherical nickel hydroxide by electroless plating, using hydrazine or sodium hypophosphite as reductive agent and ammonia or potassium sodium tartrate as complexing agent, respectively. Under the condition of the same amount of Co deposited, phases of product were detected by XRD, the morphology was observed by SEM, and its electrode discharge (1 C rate) capacity was determined. It is found that Co-coating can increase the discharge capacity by 11% to 32%.

Key words: nickel hydroxide, electroless cobalt depositing, 1 C discharge capacity
