1. A battery module comprising:
a main body accommodating individual battery cells arranged parallel to a joining axis and forming a flow channel extending transversely with respect to the joining axis for a temperature-control fluid flowing directly against cell shells of the battery cells,
wherein each battery cell has a respective burst protection sleeve that is configured so as to direct bursting of the associated battery cell to one or more ends of the battery cell, that surrounds the battery cell circumferentially with a clearance by forming an air gap, and that is mounted upstream and downstream of the flow channel in the direction of the joining axis, and
wherein the flow channel extends over a height of 28-60% of the battery cell and each burst protection sleeve extends separately over a height of 20-36% of the battery cell.
