An alkaline storage battery including a strip-shaped porous metal substrate and a material mixture filled into the substrate. The substrate has an unfilled portion where the material mixture is not filled along at least one of two longitudinal sides of the substrate. The substrate has a weight per unit area of 150 to 350 g/m. The material mixture contains an active material and an elastic polymer.

Method for producing positive electrode plate for alkaline storage battery

Positive electrode plate for alkaline storage battery and method for producing the same

The method for producing plates for batteries according to the present invention comprises: allowing X-rays to penetrate through a supplied core material, thereby calculating the weight of the core material; filling the core material with an active material; then again allowing X-rays to penetrate through the core material, thereby calculating the weight of the filled active material and the core material; calculating the weight of the active material based on the difference in these weights measured; if this weight of the filled active material deviates from a given weight, adjusting the amount of the active material to be filled in the core material, thereby inhibiting variation in the amount of the filled active material; and then drying the core material filled with the active material to make an electrode plate.
