Title:
ANODE FOR ALKALINE WATER ELECTROLYSIS AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/025208
Kind Code:
A1
Abstract:
The present invention provides an anode for alkaline water electrolysis, said anode being not susceptible to deterioration of electrolysis performance even in cases where a power with large output fluctuation such as renewable energy is used as a power source, and being capable of stably maintaining excellent catalytic activity for a long period of time. An anode 10 for alkaline water electrolysis, said anode 10 being provided with: a conductive substrate 2, at least the surface of which is formed of nickel or a nickel-based alloy; and a catalyst layer 6 which is arranged on the surface of the conductive substrate 2, while being formed of a lithium composite oxide that has a rock salt structure. With respect to this anode 10 for alkaline water electrolysis, the lithium composite oxide contains lithium (Li), nickel (Ni), iron (Fe) and aluminum (Al), and the Li/Ni/Fe/Al/O atomic ratio is (0.4-1.1)/(0.4-0.8)/(0.05-0.2)/(0.05-0.2)/2.0.
