Abstract

For the first time, the supercapacitor based on the hydrogel-polymer electrolyte which consisted of the cross-linking of polyvinyl alcohol-glutaraldehyde (PVA-GA) using 2-acrylamido-2-methyl propane sulfonic acid (AMPS) as solicitation reagent was assembled. The gel polymer electrolyte was characterized by FTIR and AC impedance. The maximum ionic conductivity is 1.23 mS/cm at room temperature. The electrochemical properties of the supercapacitor were investigated by cyclic voltammetry, AC impedance spectra and constant current charge-discharge curve. The results show that the specific capacitance reachs 139 F/g with AMPS of 1.0 g and 0.05 mL of 5 %(by mass) GA. And the specific capacitance still retained above 80% after 50 times of charge-discharge.
