Abstract: A battery includes B groups of battery cells that are arranged adjacent to one another in a stacking direction, wherein B is an integer greater than one. The B groups of battery cells include B first battery cells each having a first shape, including first groups of external tabs and defining first recesses, respectively, and B second battery cells having the first shape, including second groups of external tabs, and defining second recesses, respectively. The B second battery cells are inverted and arranged adjacent to the B first battery cells in B planes that are arranged transverse to the stacking direction. The first recesses of the B first battery cells and the second recesses of the B second battery cells define a central tunnel running through the B groups of battery cells. The central tunnel is configured to receive a temperature adjustment device.

Abstract: A battery module includes C battery cells, wherein each of the C battery cells comprises a housing and a terminals extending from the housing. T thermal interlayer devices are arranged between adjacent ones of the C battery cells. C and T are integers greater than one. Each of the T thermal interlayer devices comprises a first thermally conducting layer in thermal communication with a first one of the C battery cells, a second thermally conducting layer in thermal communication with a second one of the C battery cells, and a thermally resistant layer arranged between the first thermally conducting layer and the second thermally conducting layer. A cooling manifold is in thermal communication with at least one of the first thermally conducting layer and the second thermally conducting layer.
