Abstract
A method for filling an electrochemical cell can with a pressurized liquid electrolyte solvent and/or a liquid depolarizer. The method includes disposing an electrochemical cell system within a cell can having an open end, loosely positioning means for temporarily sealing the cell can between the open end of the cell can and the electrochemical cell system, and reducing the diameter of the open end of the cell can thereby confining the temporary sealing means between the electrochemical cell system and the open end of the cell can. The pressurized liquid electrolyte solvent and/or liquid depolarizer is introduced into the cell can. After the cell can is filled some of the electrolyte solvent and/or liquid depolarizer vaporizes. The resulting gas forces the temporary sealing means into temporary sealing engagement with the narrowed end of the cell can thereby substantially preventing loss of electrolyte solvent and/or liquid depolarizer from the cell can before the cell can is capped and permanently sealed.
