The invention relates to a battery pack comprising at least one battery cell and a housing for accommodating the at least one battery cell. It is proposed that the housing is designed as at least double-walled having at least one inner sheath and one outer sheath. According to the invention, an intermediate volume is enclosed between the at least one inner sheath and the outer sheath. The intermediate volume is able to absorb a pressure wave from an internal volume containing the battery cells.
