High-Strength and Conductive Starch/Poly(vinyl Alcohol) Hydrogel Electrolytes via Synergistic Salting-Out and Solvent Effects for Supercapacitor Applications
Conventional hydrogel electrolytes generally suffer from insufficient mechanical properties, poor low-temperature tolerance, and unsatisfactory recyclability. In this work, a starch-based hydrogel electrolyte (PS-SS) was fabricated by a simple freeze-thaw method using starch, poly(vinyl alcohol), dimethyl sulfoxide (...
