Abstract
Disclosed is a method for manufacturing an electrode by forming an electrode mixture layer on a surface of a current collector using an electrode mixture composition containing an aqueous polyimide precursor solution composition and a specific crosslinking agent, the aqueous polyimide precursor solution composition being obtained by dissolving a specific polyamide acid in an aqueous solvent together with a specific imidazole, and subsequently performing heat treatment to remove the solvent and perform an imidization reaction of the polyamide acid. It is preferable that the imidazole is an imidazole selected from the group consisting of 1,2-dimethylimidazole, 2-ethyl-4-methylimidazole, 4-ethyl-2-methylimidazole, and 1-methyl-4-ethylimidazole.
