Abstract
A battery module includes two or more battery cells and a continuous wave fin disposed between the battery cells. The construction of the wave fin is generally one-piece such that fewer parts are needed to form the battery module. In a preferred form, the wave fin is made from a high thermal conductivity material to promote removal of heat generated by the batteries during their operation. Portions of the wave fin not in direct contact with the battery cells may be placed in direct contact with a heat sink to help remove excess heat from the module. Expansion units or related additional structure may be placed, along with the various battery cells, between the generally serpentine-shaped wave fin to provide uniformity in cell spacing. A method of making one or more battery modules is also described.
