Abstract

Physicochemical properties of carbon nanofibers were evaluated as a supercacitor electrode materials could store electrochemical energy reversibly. A capacitance of carbon nanofiber electrode was increased gradually, depending on the PVDF binder ratio. A feasibility of EDLC electrode was estimated with specific surface area measurement by BET method and mesopore structure of carbon nanofiber surface could be explained electrochemical absorption-desorption in aqueous electrolyte. PVDF 5 wt.% ratio in electrode was observed a suitable binder amount by CV result.
