Composite Hydrogels With Controlled Liquid Metal Release for Dendrite‐Free Zinc Anodes
Rechargeable aqueous zinc‐ion batteries offer a cost‐effective and safe solution for large‐scale energy storage. However, uncontrolled Zn dendrite growth, parasitic hydrogen evolution, and poor Zn plating/stripping reversibility still limit their practical deployment. Herein, a Ga‐In liquid metal‐containing hydrogel el...
