A method for manufacturing a thermal interface in a battery includes providing of at least one battery module and at least one receiving structure, with a receiving region featuring a heat-transmission surface to accommodate a side of the battery module, measuring of the receiving region and/or the side of the battery module. The method further includes determining, based on the measuring, a size and shape of a gap that forms between the heat-transmission surface and the side of the battery module. Additionally, the method includes determining of a dosage specification for a heat-conducting material for filling of the gap, applying of the heat-conducting material onto the heat-transmission surface and/or to the side of the battery module according to the determined dosage specification, and installing the battery module in the intended installation position by compressing of the applied heat-conducting material.
