Abstract: Battery cells, battery cell units, battery modules, and battery assemblies are described. The cells of such components include a prismatic shaped cell housing including a slanted wall. Substantially planar positive and negative electrodes are arranged within the housing. The slanted wall defines a pocket within the housing between edges of the electrodes and an interior surface of the slanted wall and the pocket is configured to collect gas generated within the housing. A vent is formed on the slanted wall of the housing proximate the pocket. The vent is initially in a closed state and configured to open upon an increase in pressure within the housing to allow pressure and/or gases to leave the cell cavity through the vent. The battery cell units, battery modules, and battery assemblies may include such cells.

Abstract: A short circuit current limiter is disclosed which includes fuse elements configured in one of a folded back configuration or a switch back configuration, a plurality of contact terminals, one contact terminal electrically connected to each end of each fuse element, a terminal base for mechanically mounting the fuse elements and contact terminals, and a cover configured to engage the terminal base to protect the fuse elements.
