To provide a manufacturing method of an electrode for a nonaqueous electrolytic solution secondary battery having a smooth and homogeneous mixture layer superior in flexibility.
In a slurry preparation process, a mixture in which a thermosetting polyvinyl alcohol series resin and an acrylic resin series plasticizer are mixed at a weight ratio of 10 : 1, is used as a binder resin, and N-methyl-2-pyrrolidone capable of dissolving the binder resin is used as a solvent. In a mixture slurry, 2% of n-octanol of carbon number 8 of straight chain is added to the weight of an active material, and kneaded so as to become homogeneous. In an application/drying process, the mixture slurry is coated on the both faces of a current collector, and dried. In a heat-curing treatment process, thermosetting treatment of a positive and a negative electrodes dried is carried out, and thermosetting of the binder resin is carried out. Air foams formed in preparation of the mixture slurry are defoamed, and flocculation of the active material is suppressed.
