PROBLEM TO BE SOLVED: To provide a method of manufacturing a negative electrode for a nonaqueous secondary battery which is excellent in productivity, and a method of manufacturing a nonaqueous secondary battery which is excellent in safety.SOLUTION: A method of manufacturing a negative electrode for a nonaqueous secondary battery comprises a coating film forming step of coating a negative-electrode-mixture-contained composition containing a negative electrode active material, binder resin and solvent on at least one surface of a negative electrode collector to form a coating film, and a dry step of drying the coating film to form a negative electrode mixture layer. In the dry step, heating of the coating film is started to increase the surface temperature of the coating film, and subsequently the surface temperature of the coating film is adjusted so that the surface temperature of the coating film decreases and then continually stays within a range of a predetermined temperature (Ta)±5°C. Thereafter, the drying is finished at the time point when the surface temperature of the coating film decreases to (Ta+5°C)×1.2°C or less. A method of manufacturing a nonaqueous secondary battery comprises a step of manufacturing a negative electrode by the method of manufacturing the negative electrode for a nonaqueous secondary battery.SELECTED DRAWING: None |
