Synthesize and Study of Double Network Hydrogel Electrolyte for use inWearable Supercapacitors

In the last decades dual network hydrogel electrolytes are gaining intense attention in energy storagesystems because of their special electrochemical characteristics such as wide electrochemicalpotential window, high capacity to conduct both ions and electrons, mechanical and cycling stablity.In this work, a hydrogel electrolyte (HE) utilizing a natural polymer (carboxy methyl cellulose, CMC)and a conductive polymer (polypyrrole, PPy) was fabricated and leveraged in a flexiblesupercapacitor. The results of electrochemical characteristics of the present hydrogel electrolyte,including voltammetry and galvanostatic charge-discharge results showed remarkable performancecompared to liquid electrolytes.The specific capacitance of CMC-PPy-hydrogel electrolyte (CPHE)supercapacitor is almost ۲۲۷.۸ F g-۱ at the scan rate of ۵ mV s-۱.
