The patent application (Publication Number: US20240035179A1) discloses an electrode designed for use in an alkaline electrolysis process. The electrode comprises a metal substrate, a catalytic layer with nickel and nickel oxide, and an active composition containing various metal compounds such as cobalt, iridium, rhodium, iron, platinum, lithium, and manganese. The catalytic layer has a porosity of less than 1 m2/g, and the electrode's double layer capacitance falls within the range of 1.0 to 10.0 mF/g when normalized by the loading of the catalytic layer.

Furthermore, the patent application details a method for forming the electrode, involving the creation of a catalytic layer on a metal substrate through processes like thermal spraying, laser cladding, or electroplating. The active composition is then applied to the catalytic layer using precursor compositions that are heated to form the final composition. The method emphasizes the use of metal compounds like cobalt, iridium, rhodium, iron, platinum, lithium, and manganese in the active composition, with specific mole percentages for cobalt and iridium compounds. The application also includes the construction of an alkaline water electrolysis unit incorporating the electrode as an anode, along with a cathode and a chlorine-free electrolyte solution. Overall, the patent application showcases a novel electrode design and manufacturing method tailored for efficient alkaline electrolysis processes.
