Biodegradable Starch/Gelatin/PAM Hydrogel Electrolyte for Wide-Temperature Flexible Zinc-Ion Batteries.
The booming development of flexible wearable electronics requires safe, deformable, and sustainable aqueous zinc-ion batteries (AZIBs). Liquid electrolytes suffer leakage, zinc corrosion, and dendrite growth, while the recently reported hydrogel electrolytes fail to balance biodegradability and mechanical stretchabilit...
