Abstract
A battery module includes a plurality of battery cells. Each battery cell includes 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 has two adjacent battery cells with a cooling fin interposed between the two adjacent battery cells.
Claims18
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.
A battery module comprising a first subset of battery cell pairs and a second subset of battery cell pairs, each battery cell pair of the first subset including two adjacent battery cells with a cooling fin interposed between the adjacent battery cells and each battery cell pair of the second subset including two adjacent battery cells that are different than the adjacent battery cells of the first subset with a structural layer interposed between the adjacent battery cells of the second subset, wherein battery cell pairs are stacked in an alternating configuration with each battery cell pair of the second subset being positioned between battery cell pairs of the first subset.
