Claims11
A battery module comprising:
- a battery cell laminated body in which a plurality of battery cells each including an electrode assembly are stacked;
- a U-shaped frame that accommodates the battery cell laminated body therein and has an open upper part, the U-shaped frame including a bottom part and two side parts facing each other;
- and
- an upper plate covering the battery cell laminated body at the open upper part of the U-shaped frame,
- wherein one of the side parts includes a depressed part that is a portion of the one of the side parts that extends inward toward the battery cell laminated body relative to a periphery of the one of the side parts, and an area of the depressed part is equal to or larger than an area of the electrode assembly,
- wherein the depressed part is formed of an elastic member that is configured to provide an elastic force in the stacking direction of the plurality of battery cells, and
- wherein the battery cell laminated body further includes a plurality of double-sided adhesive tapes each positioned between adjacent ones of the plurality of battery cells, respectively.
