Abstract
Official abstract text for this publication.
A method for manufacturing an electrode for electrolysis, which includes applying a coating composition on at least one surface of a metal substrate, and drying and heat-treating the metal substrate applied with the coating composition to form a coating layer, in which urea and octadecylamine are both used in the coating composition to improve the durability and performance of an electrode for electrolysis to be manufactured.
First claim
Opening claim text (preview).
1 . A method for manufacturing an electrode for electrolysis, the method comprising: applying a coating composition on at least one surface of a metal substrate; and drying and heat-treating the metal substrate coated with the coating composition to form a coating layer, wherein the coating composition includes a ruthenium precursor and a stabilizer, wherein the stabilizer includes urea and octadecylamine. 2 . The method of claim 1 , wherein the urea and the octadecylamine are included at a molar ratio of 90:10 to 10:90. 3 . The method of claim 2 , wherein the urea and the octadecylamine are included at a molar ratio of 80:20 to 60:40. 4 . The method of claim 1 , wherein the ruthenium precursor and the stabilizer are included at a molar ratio of 100:20 to 100:40. 5 . The method of claim 1 , wherein the coating composition further comprises a cerium precursor. 6 . The method of claim 1 , wherein the coating composition further comprises a platinum precursor. 7 . The method of claim 1 , wherein a solvent of the coating composition is a mixture of isopropyl alcohol and 2-butoxy ethanol. 8 . The method of claim 1 , wherein the applying, the drying, and the heat-treating are repeatedly performed such that a content of a ruthenium oxide is 7 g/m 2 or greater per unit area of the electrode for electrolysis. 9 . The method of claim 1 , wherein the drying is performed for 5 minutes to 60 minutes at 50° C. to 300° C. 10 . The method of claim 1 , wherein the heat-treating is performed for 1 hour or less at 400° C. to 600° C.
