Title:
A manufacturing method of a nonaqueous electrolyte secondary battery
Document Type and Number:
Japanese Patent JP6224399
Kind Code:
B2
Abstract:
An organic acid included in a nonaqueous electrolyte solution of a battery is reduced. During preparation of a film-covered battery 1, the nonaqueous electrolyte solution is injected into a covering 5 of the film-covered battery 1 having an electrode including: the electrode active material, the binder, and the organic acid, the organic acid in the nonaqueous electrolyte solution is decomposed by electrical charging of a battery until a voltage level is equal to or above a decomposition voltage of the organic acid, and the gas that is produced by decomposition is degassed from the cut portion 6 of the covering 5 .
