ALKALI STORAGE BATTERY

PROBLEM TO BE SOLVED: To prevent a lowering of capacity caused by an omission of a cathode activation material by giving a structure preventing infiltrated reaction at cathode plates even though arranging anode plates so as to shift from cathode plates. SOLUTION: An anode activation material slurry is made by adding binding agent to the powder of hydrogen absorbing alloy, and both surface of punching metal 12a is coated by anode activation material slurry, and rolled into prescribed thickness after drying, and cut into prescribed shape. Afterwards, an exposed part 12b of the punching metal 12a, as an anode plate 12 of the hydrogen absorbing alloy, is formed by scraping off the anode activation material on the area with subscribed width at the lower end part. After arranging the anode plate 12 and a nickel cathode plate 11 so as to shift from each other in the direction of upside and downside, a swirl- shaped electrode group 10 is formed by winding into swirl shape interposing a separator 13. After welding a cathode current collector 14 and an anode current collector 15 to the upper part and lower part of the swirl-shaped electrode group 10 respectively, a nickel-hydrogen storage battery is formed by inserting the above assembled body in a metal container, pouring electrolyte, and sealing an aperture by sealing body.
