Abstract
A lithium ion battery module includes a housing having a thermally conductive base and a cell assembly disposed within the housing and comprising pouch battery cells, a plurality of layers interleaved with the pouch battery cells, and a pair of end plates disposed on opposite ends of the cell assembly to compress the pouch battery cells. The battery cells are held within the cell assembly by cell frames. Each cell frame is formed from two frame pieces. The plurality of layers comprises a plurality of foam sheets and a plurality of thermally conductive sheets. The foam sheets are configured to allow swelling of the pouch battery cells while enabling a substantially constant level of compression of the pouch battery cells by the pair of end plates. The thermally conductive sheets conduct heat from the battery cells toward the thermally conductive base of the housing.
