Abstract: 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 deg, 22 deg, 33.5 deg, 60 deg. This suggests that the samples obtained are highly crystalline (orderliness) in nature with a motif. The nickel hydroxide with alpha-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.
Licensing Option: Laboratory scale know-how is available.
