Abstract:
1. A battery module comprising a plurality of stacked battery cells, each battery cell including an anode having an anode active area, a cathode having a cathode active area, and an ion-conducting separator interposed between the anode active area and the cathode active area, a first subset of the battery cells are arranged in parallel wired battery cell pairs, each parallel wired battery cell pair of the first subset including two adjacent battery cells with a cooling fin interposed between the two adjacent battery cells and a second subset of the battery cells are arranged in parallel wired battery cell pairs, each parallel battery cell pair of the second subset including two adjacent battery cells that are different than the battery cells in the first subset, and a thermally insulating layer interposed between the two adjacent battery cells of the second subset.
