The non-aqueous electrolyte secondary battery

In the non-aqueous electrolyte secondary battery, in the case where the lid sealing structure and the electrode terminal configuration is to compress the sealing member by tightening the nut, there may occur the following problems: a sealing member can be obtained even when the cell producing a suitable the amount of compression bolts fastened, then if the bolt is loose, the amount of compression of the sealing member is insufficient, resulting in reduced sealing performance. The non-aqueous electrolyte secondary battery of the present invention is configured to have the following structure: a battery accommodating groove electrode group and an organic electrolyte solution and having an opening portion, the opening portion is fastened to the battery slot and battery container sealed with a lid and the electrode group an electrode terminal electrically connected via the elastic body opposite.
