Patent ID: 7662516

Claim:
A method for manufacturing an electrode plate of a positive electrode for a non-aqueous secondary battery comprising the steps of: (a) preparing an active material A, a conductive material B, a binder C, a thickener D, and a liquid component E, said thickener D being in a powder state and being soluble in said liquid component E, said conductive material B comprising at least a carbon material, said thickener D comprising at least a water-soluble polymer, and said liquid component E comprising at least water, (b) preparing a slurry comprising said liquid component E and an electrode material mixture comprising said active material A, said conductive material B, said binder C, and said thickener D, and (c) applying said slurry on a current collector, wherein said step (b) includes kneading said thickener D in a powder state, said active material A and said conductive material B together with said liquid component E to prepare a primary kneaded matter, and then kneading said primary kneaded matter, said binder C, and an additional liquid component to prepare said slurry as a secondary kneaded matter, wherein a viscosity of an aqueous solution dissolving 1 wt % thickener D is 2.5 to 18 Pa·s at 25° C.
