An electrochemical cell comprising a conductive casing housing an electrode assembly provided with a stack holder surrounding the electrode assembly is described. The stack holder is of an elastic material that serves to maintain the anode and cathode in a face-to-face alignment throughout discharge. This is particularly important in later stages of cell life. As the cell discharges, anode active material is physically moved from the anode to intercalate with the cathode active material. As this mass transfer occurs, the cathode becomes physically larger and the anode smaller. This can lead to misalignment. However, the stack holder prevents such misalignment by maintaining a constrictive force on the electrode assembly throughout discharge.
