摘要
The present invention provides an improved process for the preparation of battery grade nickel hydroxide by electrochemical method using ethanol as solvent. The raw material used I the present invention is nickel solution from nickel nitrate and commercially available 99.9% ethanol. In some cases cobalt was added as additives to increase the utilization of nickel hydroxide electrode. The XRD graph obtained with sharper and narrow peak with peaks at 11°, 22°, 33.5°, 60°. This suggests that the samples obtained are highly crystalline (orderliness) in nature with a motif. The nickel hydroxide with α-formed was identified in all the cases. A maximum tapped density of 1.87g/cc was observed and specific discharge capacity per one gram of nickel hydroxide was observed to vary in the range of 200-215 mAh, when discharge rate was 80mA.
