Abstract
A battery module comprises a battery sub-module including one or more battery cells, and a barrier disposed to face one side surface of the battery sub-module, in which the barrier includes a rigid member supporting the battery sub-module, and a heat absorbing member accommodated in the rigid member to absorb heat generated by the one or more battery cells.
Claims16
A battery module, comprising:
- a first battery sub-module and a second battery sub-module stacked in a first direction, each of the first and second battery sub-modules including a plurality of battery cells and a side plate at least partially contacting at least one of the plurality of battery cells;
- and
- a barrier disposed between the side plate of the first battery sub-module and the side plate of the second battery sub-module,
- wherein the barrier includes:
- a first base facing the side plate of the first battery sub-module;
- a second base facing the side plate of the second battery sub-module;
- a heat absorbing member is included in the barrier to absorb heat generated by the battery cells and disposed to overlap with the side plate of the first battery sub-module and the side plate of the second battery sub-module in the first direction;
- a protrusion portion continuously extending along an edge region of the first base and an edge region of the second base, respectively, protruding toward the side plate of the first battery sub-module and the side plate of the second battery sub-module, and pressing against an edge region of the side plates of the first and second battery sub-modules in the first direction;
- a first air gap enclosed by the first base and the side plate of the first battery sub-module and the protrusion portion;
- and
- a second air gap enclosed by the second base and the side plate of the second battery sub-module and the protrusion portion.
