摘要：

Nickel hydroxide has been prepared chemically and electrochemically from sulfate and nitrate media respectively. The effect of bimetallic additives Cd-Zn, Cd-Mn, Cd-Co, Cd-Fe, Cd-Al during chemical precipitation on discharge capacity has been studied. A discharge capacity of 190 mAh/g of nickel hydroxide was observed for nickel hydroxide precipitated in presence of Cd and Al; and a capacity of 200 mAh/g was obtained with a sample that was produced electrochemically at a current density of 50 A/m(2).
