A Biobased Hydrogel Electrolyte for Stable Zinc Anodes via Regulation of the Local Water Environment
Aqueous zinc metal batteries are attractive for safe and low-cost energy storage, yet their practical application remains limited by water-induced parasitic reactions and unstable zinc deposition at the anode/electrolyte interface. Herein, a bio-based gelatin/poly(γ-glutamic acid) hydrogel electrolyte is developed to...
