Abstract
Presented are terminal end caps for pouch-type battery cells, vehicles equipped with rechargeable battery packs containing such pouch cells, and methods for making/using such caps, cells, and/or vehicles. A battery cell assembly includes a cell pouch with flexible pouch walls that are joined along a peripheral seam to define one or more openings at one or both ends of the cell pouch. Located inside the cell pouch is an ion-conducting electrolyte and one or more pairs of working electrodes in electrochemical contact with the electrolyte. Also located inside the cell pouch and interposed between each pair of working electrodes is an electrically isolating separator sheet. A terminal end cap is located in each pouch opening and attached to the pouch walls. Each terminal end cap includes a rigid polymeric cap body with one or more electrical terminals embedded in the cap body and electrically connected to at least one electrode.
