1. A method for producing an anode for alkaline water electrolysis, the method comprising:dissolving lithium nitrate and a nickel carboxylate in water so as to obtain an aqueous solution comprising lithium ions and nickel ions,
applying the aqueous solution to a surface of a conductive substrate, wherein at least the surface of the substrate comprises nickel or a nickel-based alloy, and
subjecting the conductive substrate to which the aqueous solution has been applied to a heat treatment at a temperature within a range from 450° C. to 600° C., thereby forming a catalyst layer comprising a lithium-containing nickel oxide on the conductive substrate,
wherein the lithium-containing nickel oxide is represented by a compositional formula LixNi2?xO2, wherein x is 0.02?x?0.5.
