Abstract: A holding device for battery cells for constructing a high-voltage storage module which can be used for electrically operated motor vehicles is provided. The battery cells, in a P assembly (i.e. interconnected in parallel), are provided with a minimally thin thermal insulating layer and, encased in this way, are brought into direct contact with each other in a self-holding arrangement. The intermediate spaces between the battery cells, which battery cells have been provided with the insulating layer and, encased in this way, have been brought into contact with each other, are preferably filled with a thermally conductive potting compound. The thermally conductive potting compound can additionally have high electrical conductivity and thus, in addition to the heat transfer, can also establish the contacting of the anodes in the P assembly if the anodes are also encased by the potting compound.

The frame laterally separates each battery cell from the other battery cells. A further fire-retardant coating is preferably additionally applied directly onto a housing of the battery cells. An air gap can be provided between each battery cell and each separation chamber of the frame.
