Claims12
A battery module, comprising:
- a battery cell stack in which a plurality of battery cells are stacked in a first direction along a length of the battery cell stack, each battery cell of the plurality of battery cells having a cross sectional shape and a length extending in a second direction, the length of each battery cell being equal to a width of the battery cell stack in the second direction;
- a plurality of flame spread prevention members, each of the plurality of flame spread prevention members comprising a first side wall extending in a second direction and configured to contact a first side of a respective one of the plurality of battery cells;
- and
- a case configured to accommodate the battery cell stack covered by the plurality of flame spread prevention members,
- wherein a plurality of hollows is formed by the plurality of flame spread prevention members so that each of the plurality of battery cells is inserted into a respective one of the plurality of hollows,
- wherein a cross sectional shape of the plurality of hollows is the same as a cross sectional shape of the respective one of the plurality of battery cells,
- wherein each of the plurality of flame spread prevention members includes a second side wall extending from the first side wall to cover a second wall of a respective one of the plurality of battery cells, and
- wherein each of the plurality of battery cells is a pouch-type battery cell having a rectangular shape, and each of the plurality of flame spread prevention members has a hexahedral shape with two open ends.
