Chemical Plating of Cobalt on Ni(OH)2 Spheres and the Discharge Performance of Electrodes Made Thereof
球形氢氧化镍表面镀覆钴的结构与电极1 C倍率放电容量

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%.
