ABSTRACT:
Provided are a method for preparing a nickel hydroxide for a nickel electrode, which comprises solidly dissolving ions of other metals than nickel in a nickel hydroxide, and eluting a partial amount of the metal, a method for manufacturing a nickel electrode, which comprises filling a porous current collector with an active material paste consisting mainly of the resulting nickel hydroxide, and an alkaline secondary battery which incorporates the nickel electrode as a positive electrode therein. This nickel hydroxide restrains deformation or expansion of the nickel electrode and lowering of the discharge capacity of the battery despite repeated charge/discharge cycles of the battery.
