ELECTROCHEMICAL CELL WITH ELECTRODE ELEMENTS THAT INCLUDE ALIGNMENT APERATURES

摘要

A battery comprises a battery case forming a substantially sealed enclosure and an electrode stack within the enclosure. The electrode stack includes a first set of electrode elements and a second set of electrode elements. The electrode elements in the second set alternate with the electrode elements in the first set within the electrode stack. In addition, the electrode elements include coincident alignment apertures. The coincident alignment apertures are configured to restrict rotation of the electrode elements to align the electrode elements when the alignment apertures are positioned over mating alignment protrusions during assembly of the electrode stack. The battery further comprises a feedthrough including a feedthrough pin extending through the battery case. The feedthrough pin is electrically coupled to the electrode stack and serves as a positive terminal for the battery.
