Electrolysis electrode and method for manufacturing same

An anode of an electrolysis cell comprising:

• an electrically conductive substrate at least a surface of which comprises nickel or a nickel-based alloy;
• an intermediate layer formed on the surface of the electrically conductive substrate and comprising a lithium-containing nickel oxide represented by composition formula LixNi2-xO2, wherein x is in a range from 0.3 to 0.5;
• and
• a catalyst layer formed on a surface of the intermediate layer,
• wherein the catalyst layer comprises at least one catalyst selected from the group consisting of a nickel cobalt spinel oxide, a lanthanide nickel cobalt perovskite oxide, and a lithium nickel cobalt oxide,
• wherein the intermediate layer has a layer average density in a range from 5.1 g/cm3 to 6.0 g/cm3, and
• wherein the intermediate layer is a layer formed by heat-treating a precursor thereof at a temperature in a range from 450° C. to 600° C. on the surface of the electrically conductive substrate.
