Experimental studies and model validation thereof on all solid-state electrical double layer capacitors (EDLCs) comprising of a novel, cost-effective, and eco-friendly electrode binder consisting of chitosan chemical hydrogel (CCH), and a separator consisting of ionically cross-linked chitosan hydrogel membrane electrolyte (ICCSHME) are reported. The EDLCs have been assembled with black pearls carbon as electrode. The ICCSHME has been prepared by ionic cross-linking of chitosan (CS) with sodium sulfate. EDLCs comprising 40 % loading of CCH electrode binder and ICCSHME with 1 M NaOH dopant have been studied by galvanostatic chronopotentiometry. The data have been analyzed using mathematical modeling to study lifetime behavior of the EDLCs.
