Abstract
A battery is provided including a battery cell having main top and bottom surfaces, and a plurality of side surfaces; and at least one resin section including a cured resin that covers at least three of the plurality of side surfaces of the battery cell, but that does not cover substantially all of the top and bottom surfaces of the battery cell.
Claims25
A battery comprising:
- a battery cell having main top and bottom surfaces, and a plurality of side surfaces;
- and
- at least one resin section including a cured resin that covers at least three of the plurality of side surfaces of the battery cell, but that does not cover substantially all of the top and bottom surfaces of the battery cell,
- wherein the battery cell includes a cell main body including a battery element, and an exterior material that covers the battery element, the resin sections being formed on the exterior material,
- wherein the exterior material includes a fusion portion that is folded back to contact the cell main body,
- wherein a height (D) of at least one of the resin sections and a height (B) of the folded back part of the fusion portion satisfy the following relationship D>B, and.
- wherein at least part of one of the resin sections contacts and is formed between the folded back part of the fusion portion and the cell main body.
