  • the invention relates to a rechargeable battery having at least one, preferably with a plurality of battery cells, which are arranged in frame elements, wherein the frame elements comprise a base body made of foamed material, and the frame elements each comprise a first transverse belt, a second transverse belt opposite the first transverse belt and two Having opposite longitudinal straps.
  • Rechargeable batteries so-called accumulators are found in all areas of technology. In the automotive industry, such accumulators are used for alternative drive systems, with high demands being placed on performance, reliability and maintenance of the battery cells used in this area. In particular, the size and weight of such batteries are a major factor in their efficiency in automotive operation.
  • the rechargeable batteries used in this case usually consist of a large number of battery cells, which are combined in cell stacks, in so-called modules, and connected to one another.
  • Such cells are sensitive to mechanical stress and vibrations, in particular when so-called pouch cells are used, so that in the prior art such cells are fixed in usually rigid cell frames and these frames are lined up in cell stacks.
  • changes in thickness occur during a charge / discharge cycle that must be balanced within the cell stack. Likewise, if necessary, manufacturing tolerances must be compensated.
  • the arrangement of battery cells in a cell frame can be found, for example, in WO 2011/057815 A1 or DE 10 2010 051 010 AI. These solutions can only be used to a limited extent for so-called Poch cells because they can only insufficiently counteract mechanical loads that can occur in motor vehicles or the changes in thickness during operation.
  • US 2007/259258 A1 describes a battery cell which is arranged in a foamed frame element. A similar arrangement can also be found in JP 2001/273887 A.
