METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To facilitate the alignment between positive and negative electrode mixture parts in manufacturing a nonaqueous electrolyte secondary battery having an electrode-winding body.SOLUTION: A method for manufacturing a nonaqueous electrolyte secondary battery comprises a process for obtaining a negative electrode plate 20 which includes: a step α where a first negative electrode mixture part 22a and an uncoated part wider than a foil-exposed part N2 are formed by intermittently coating an outer peripheral principal face with a negative electrode paste; and a step β where a second negative electrode mixture part 22b of a sheet-like form narrower than the uncoated part is obtained by compression-molding a negative electrode granulated body higher than a negative electrode paste in solid content ratio, and the second negative electrode mixture part 22b is disposed on the uncoated part so that the first negative electrode mixture part 22a and the second negative electrode mixture part 22b are connected with each other.SELECTED DRAWING: Figure 9
