Abstract:
Provided is a method capable of producing, in a simple and low-cost manner, an electrolysis electrode which can be used in alkaline water electrolysis and has superior durability against output variation. The method for producing an anode for alkaline water electrolysis includes: a step of dissolving lithium nitrate and a nickel carboxylate in water to prepare an aqueous solution containing lithium ions and nickel ions, a step of applying the aqueous solution to the surface of a conductive substrate having at least the surface composed of nickel or a nickel-based alloy, and a step of subjecting the conductive substrate to which the aqueous solution has been applied to a heat treatment at a temperature within a range from at least 450° C. to not more than 600° C., thereby forming a catalyst layer composed of a lithium-containing nickel oxide on the conductive substrate.
