ABSTRACT:
A positive electrode plate for alkaline storage battery that does not swell very much even after repeated charge-discharge cycles and can be manufactured easily, a method for manufacturing the same, and an alkaline storage battery using the same are provided. A conductive support (nickel foam) and an active material (nickel hydroxide particles) that is supported by the support are provided. An intermediate part of a positive electrode plate has a larger porosity than surface parts thereof.
