Polarization studies have indicated the occurrence of three reactions on the cathode surface during precipitation of nickel hydroxide. Out of these, the nitrite-forming reaction followed by conversion to ammonium ion might be the reaction path. The reaction scheme is well supported by the trends in variations of open-circuit potential. Detailed prolonged galvanostatic precipitation studies have shown that the (OH)/C0/Ni2þ ratio plays an important role in determining the phase of nickel hydroxide. A ratio of (OH)/C0/Ni2þ higher than 6, with sufficient nickel ion in the bath, ensures β-nickel hydroxide with larger particles and less H2O molecules within. Maintaining these ratios at lower levels forms α-nickel hydroxide with finer size and a higher number of H2O molecules within. The mechanism of these product formations has been explained in the paper. It is also observed that finer size with a higher surface area and more H2O molecules in the crystal structure results in higher discharge capacity.
