ABSTRACT:
An electrochemical cell of the type having a spirally wound electrode assembly contained within a cell case, wherein the case is provided with inwardly directed deformed wall portions which engage the electrode assembly to restrain it against movement within the case. External electrical terminals are physically affixed to the electrode assembly at predetermined locations relative to the terminal ends of the spirally wound electrodes; such terminals are used to physically align the cells prior to deforming the case to ensure that the deformed wall portions of the case are displaced from the terminal ends of the electrodes, thereby avoiding undue stress upon the electrode assembly.
