1. A battery module comprising:
a plurality of cell stacks, each of the cell stacks comprising:
a plurality of unit cells arranged in a first direction; and
an insulation member around the plurality of unit cells; and

a module housing, in which a plurality of receiving parts are provided, each of the cell stacks from among the plurality of cell stacks being located in a receiving part from among the plurality of receiving parts,
wherein each of the receiving parts comprises a fixing wall, the fixing wall being around the cell stack received therein and being in contact with the cell stack,
wherein the module housing comprises a floor surface and end walls extending from the floor surface, the end walls comprising a first end wall and a second end wall at respective sides of each of the receiving parts in the first direction to engage end surfaces of respective sides of the cell stack received in the respective receiving part in the first direction,
wherein the first end wall faces an outer wall of the module housing and is spaced apart from the outer wall along the first direction, defining a first space between the first end wall and the outer wall,
wherein the end walls are curved outwardly such that central portions thereof are located further from the end surfaces of the cell stacks than other portions of the end walls, defining a third space between the respective end surface and the respective end wall,
wherein each of the cell stacks further comprises a pair of end supports at opposite end portions thereof in the first direction and having end surfaces corresponding to the end surfaces of the respective cell stack, and
wherein the end surfaces of the end supports are recessed inwardly so that central portions thereof are further from the respective end wall than other portions of the respective end surface of the respective end support.
