Alkaline rechargeable batteries and process for the production of said rechargeable batteries

摘要

An alkali rechargeable battery having an anode principally comprising a magnesium-nickel alloy capable of storing hydrogen therein and releasing said hydrogen stored therein in electrochemical reaction, wherein said magnesium-nickel alloy constituting said anode has a surface having a coat layer provided thereon, and said coat layer comprises an insulating material which is not dissolved in an electrolyte solution comprising an aqueous alkali solution used in said rechargeable battery, which restrains a reaction which cases a magnesium hydroxide when said magnesium-nickel alloy contacts with said electrolyte solution, and which allows hydrogen or hydrogen ion to pass therethrough. A process for the production of said rechargeable battery.
