Document Type and Number:
Japanese Patent JP4772185
Kind Code:
B2
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 11) and an active material (nickel hydroxide particles 12) that is supported by the support are provided. An intermediate part of a positive electrode plate (10) has a larger porosity than surface parts thereof. Processing of the electrode includes two subsequent pressing steps using two pairs of rollers. For each of the pressing step the diameter of the rolls and the pressure applied to the support are different.
