Abstract: A cell assembly for an electrochemical energy storage device has: two cells for electrochemically storing electric energy; and a first insulating body for thermally insulating the two cells from each other. The insulating body is arranged between the cells in an intermediate space delimited by a respective lateral surface of each of the two cells and is configured to absorb pressure exerted by the lateral surfaces of the two cells on lateral surfaces of the first insulation body, where compression occurs along a compression direction. The insulating body includes a first thermally insulating and compressible fiber material and has a rigidity as a function of compression, where a value curve of the rigidity has a first compression value section and a second compression value section adjoining the first compression value section. A cell module has a cell assembly and a high-voltage storage device has a cell module as described herein.

Abstract: A carrier board element is provided for the cell connectors of a battery having a plurality of battery cells. The carrier board element has a plurality of cell holders uniformly spaced apart from each other. At least one locking element for the locking in of a cell connector is associated with each of the cell holders. The locking element is arranged on the carrier board element. A plurality of cell connectors can be captively locked in one over the other at the locking elements.
