Abstract
An organic acid included in a nonaqueous electrolyte solution of a secondary battery is reduced. During preparation of a film-covered batterythe nonaqueous electrolyte solution is injected into an coveringof the film-covered batteryhaving 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 portionof the covering
