A battery module for a partially or fully electrically operated vehicle, having a battery housing, which has a main body with at least one open end, and at least one battery cell stack, which has a carrier plate at least at one end. The battery cell stack has been introduced into the main body such that the carrier plate substantially closes off the open end of the main body. On the carrier plate, there is provided an at least sectionally peripheral seal, which projects from the carrier plate and bears at least sectionally against the inner surface of the main body. The seal is of air-permeable form, so that, during the introduction of a fluid of relatively high viscosity into an intermediate space between the battery cell stack and the inner surface of the main body, displaced air can escape from the main body through the seal.
