Stretchable, Wide-Temperature Gel Electrolytes Integrating Ionic Conduction and Heat Buffering for Flexible Supercapacitors.
Traditional hydrogel electrolytes face multiple challenges in flexible energy storage applications, including poor mechanical properties, low ionic conductivity, and failure under extreme temperatures. Herein, this study designs and fabricates a composite gel electrolyte based on polyacrylic acid (PAA), cellulose nanof...
