Abstract
The purpose of this project is to research and development of thin film supercapacitor with conducting polymer composite electrodes and polymer electrolyte which have high energy density for thin film supercapacitor. We investigated cyclic voltammetry and charge/discharge cycling of PFPT-flyash electrodes. The first discharge capacity of PFPT-flyash electrode with 40wt.% flyash was 24F/g, while that of PFPT-VOflyash electrode with 40wt.% VOflyash was 32F/g. The capacitance of PFPT-VOflyash composite film with polymer electrolyte was 32 F/g at 1st and 20th cycle, respectively. The capacitance of PFPT-VOflyash/Li cell with 40 wt% VOflyash was 141 F/g at 8th cycle.
