Abstract

A battery device includes a case, a cell disposed within the case, and first and second conductive tabs each electrically connected to the cell and partly enclosed by the case. The first conductive tab has an elastic portion exposed from the case and compressible or stretchable when a force is applied thereto. By having the elastic portions that are elastically deformable, the effects of push or pull resulting from the swelling of the cell and case on the conductive tabs may be reduced. Consequently, damages or breakages of the conductive tabs can be avoided and the safety of battery device may be improved.
