ACTIVE MATERIAL SUPPORT FOR BATTERY USING FOAMED METAL POROUS BODY AND ITS MANUFACTURE, NON-SINTERED ELECTRODE FOR ALKALINE STORAGE BATTERY USING THIS ACTIVE MATERIAL SUPPORT AND ITS MANUFACTURE, AND ALKALINE STORAGE BATTERY USING THE NON-SINTERED ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide an alkaline storage battery with high capacity, good high rate discharge characteristics by preparing an electrode which generates no chipping or breakages even in spiral winding so as to have a margin in the elongating direction of a belt-shaped metal plate and preventing the coming off of the belt-shaped metal plate from a metal porous body. SOLUTION: An active material support alternately has a melt bonded part 12a to a foamed metal porous body 11 and a non-melt bonded part 12b in a belt-shaped metal plate 12, and the length of the non-melt bonded part 12b is made longer than a distance D between the melt bonded parts 12a. By alternately forming the melt bonded parts 12a and the non-melt bonded parts 12b, the sufficient melt bonding strength can be obtained by adjusting the distance between the melt-bonded parts 12a. When the length of the non-bonded part 12b is made longer than the distance D between the melt bonded parts 12a, the belt-shaped metal plate 12 produces a margin in the extending direction, and the generation of breakages in the belt-shaped metal plate 12 can be prevented even if it is wound spirally.
