Capacitance Stability of Supercapacitor from Activated Carbon/PVDF Electrode

摘要

The aim of research was to be aware stability of supercapacitor capacitance for 50 cycles. Supercapacitor device in this research was fabrication into sandwich form, that consist a pair of activated carbon/10 wt% PVDF electrode separated with hydrogel polymer. Furthermore do characterization using cyclic voltammetry for 50 cycles with 1 M Na_2SO_4 electrolyte solution at the scan rate 5 mV/s. The result of this research show that supercapacitor device with activated carbon/10 wt% PVDF capacitance stability 39 F/g at 50 cycles.
