Claim 0:
1. An alkaline water electrolysis anode comprising:
an electrically conductive substrate at least a surface of which comprises nickel or a nickel base alloy;
an intermediate layer on the electrically conductive substrate; and
a catalyst layer disposed on a surface of the intermediate layer, the catalyst layer comprising a nickel-containing metal oxide having a spinel structure,
wherein the intermediate layer disposed between the electrically conductive substrate and the catalyst layer comprises a lithium-containing nickel oxide represented by compositional formula LixNi2-xO2 wherein x is in a range of 0.02≤x≤0.5, and
the nickel-containing metal oxide comprises nickel (Ni) and manganese (Mn), and has an atom ratio of Li/Ni/Mn/O in a range of (0.0 to 0.8)/(0.4 to 0.6)/(1.0 to 1.8)/4.0.
