A silk fibroin hybrid hydrogel electrolyte enables highly robust aqueous zinc-ion batteries to operate from −60 to 60 °C
Aqueous zinc-ion batteries (AZIBs) enable safe and sustainable grid-scale energy storage but are limited by dendrite growth, parasitic reactions, and poor temperature tolerance. Herein, we report a multifunctional silk fibroin/polyacrylamide hydrogel electrolyte (SF/PAM-HGE) enabling stable zinc electrochemistry from −...
