An electrochemical storage cell is disclosed that comprises a core and a rectangular shell that receives the core snugly therein. The rectangular shell has first and second open ends. A first end cap is used to close the first open end. An anode terminal extends through the first end cap from an interior portion of the electrochemical storage cell to an external portion thereof. A first gasket is secured within the rectangular shell between the first end cap and the core to resiliently hold the core away from the first end cap. A second end cap is used to close the second open end. A cathode terminal extends through the second end cap from an interior portion of the electrochemical storage cell to an external portion thereof. A second gasket is secured within the rectangular shell between the second end cap and the core to resiliently hold the core away from the second end cap.
