Abstract
A battery cell includes a case and an electrode stack disposed within the case. The battery cell includes an anode including a first conductive tab, a cathode including a second conductive tab, and a separator. The battery cell further includes two electrical connections, each attached to one of the first conductive tab or the second conductive tab and to one of a negative terminal and a positive terminal, respectively. The anode, the cathode, and the separator each include a common perimeter including a first portion matching a shape of an interior surface of the case and a second portion including a cut-out configured to recede from the interior surface. The second portion of the anode, the cathode, and the separator are aligned and create a region between the stack and the interior surface. The tabs and electrical connections are disposed within the region.
