Abstract
A method for forming a thermally conductive connection between a plurality of battery cells (2) and a temperature-regulating body (1) of a battery module (100), wherein, in a first method step, an adhesive (3) comprising at least one first component (31) and at least one second component (32) is applied to the temperature-regulating body (1) or to the plurality of battery cells (2), wherein a first proportion (41) of the at least one first component (31) and/or a second proportion (42) of the at least one second component (32) is changed during the application of the adhesive (3) over the temperature-regulating body (1) or the plurality of battery cells (2), wherein, in a second method step, the plurality of battery cells (2) is connected to the temperature-regulating body (1) in such a way that an inhomogeneous material bond is formed between the plurality of battery cells (2) and the temperature-regulating body (1).
