Abstract
A hydrogel electrolyte for a supercapacitor includes sodium carboxymethyl cellulose (C), water, citric acid (CA); and an aqueous extract of. The sodium carboxymethyl cellulose (C) and the citric acid (CA) form a citric acid cross-linked cellulose-based polymer hydrogel (C-CA-C). An organic acid from the aqueous extract ofis intercalated to the citric acid cross-linked cellulose-based polymer hydrogel (C-CA-C) via hydrogen bonds. A method of preparation of the hydrogel electrolyte is also discussed.
