Carbon film electrodes for super capacitor applications
Patent
·
OSTI ID:20014166
A microporous carbon film for use as electrodes in energy storage devices is disclosed, which is made by the process comprising the steps of: (1) heating a polymer film material consisting essentially of a copolymer of polyvinylidene chloride and polyvinyl chloride in an inert atmosphere to form a carbon film; and (2) activating said carbon film to form said microporous carbon film having a density between about 0.7 g/cm{sup 2} and 1 g/cm{sup 2} and a gravimetric capacitance of about between 120 F/g and 315 F/g.
