ABSTRACT:
The tap density of nickel hydroxide powders is improved, the expansion of a positive electrode is inhibited and the energy density of the positive electrode and the cycle life characteristics are improved by specifying the shape of the nickel hydroxide powders and besides, adding to the nickel hydroxide powders at least one of Cd, Ca, Zn, Mg, Fe, Co and Mn. The nickel hydroxide active material powders contain 1-7 wt % of at least one of Cd, Ca, Zn, Mg, Fe, Co and Mn and comprise a mixture of spherical or nearly spherical particles and non-spherical particles.
