Abstract

A battery module, in particular for a motor vehicle, encompassing at least one battery cell that is received, in a manner impinged upon by compressive force along a spacing axis, between two pressure surfaces arranged with a spacing from one another along the spacing axis and clamped toward one another; at least one interlayer additionally being provided along the spacing axis between the pressure surfaces; the interlayer, constituting an LWRT interlayer, encompasses a porous LWRT material having a thermoplastically bonded fiber tangle.
