Patent ID: 8277520

Claim:
A method for producing a negative electrode for a non-aqueous electrolyte secondary battery comprising: a paste preparing step of kneading a mixture containing a negative electrode active material, a binder resin having a glass transition temperature within a range from 20 to 40° C. and a dispersion solvent to prepare a negative electrode material mixture paste at a temperature at least 10° C. higher than the glass transition temperature of the binder resin, wherein the binder resin consists of one kind of a styrene-butadiene-based copolymer in a form of an emulsion containing the resin having a particle size of 0.01 to 0.1 μm, a paste applying step of applying the negative electrode material mixture paste controlled to a temperature which is at least 20° C. higher than the glass transition temperature of the binder resin on a current collector to form a coating film, a coating film drying step of drying the coating film by heat-treating in an atmosphere at 120° C. or higher to form a negative electrode precursor, a rolling step of rolling the negative electrode precursor using a rolling device at a temperature same as the glass transition temperature or lower to prepare a negative electrode having a negative electrode material mixture layer, and a heat treating step of heat-treating the negative electrode in an atmosphere at 150° C. or higher.
