Abstract:
A method of fabricating a component cell of an electric double layer capacitor, comprising the steps of:a) forming a first half portion of the cell by pasting a first polarized electrode impregnated with electrolyte to a first collector electrode so that a first stepped portion is formed on the periphery of the first collector electrode and attaching a first gasket to the first stepped portion; b) forming a second half portion of the cell by pasting a second polarized electrode impregnated with electrolyte to a second collector electrode so that a second stepped portion is formed on the periphery of the second collector electrode and attaching a second gasket to the second stepped portion; c) attaching a third gasket to the periphery of a separator and placing the separator between said first and second half portions of the cell; and d) applying pressure to said first and second half portions of the cell in directions towards each other at an elevated temperature so that said first and second gaskets are thermally joined with said third gasket.
