Abstract
Abstract The large‐scale applicability of Zn‐metal anodes is severely impeded by the issues such as the dendrite growth, complicated hydrogen evolution, and uncontrollable passivation reaction. Herein, a negatively charged carboxylated double‐network hydrogel electrolyte (Gelatin/Sodium alginate‐acetate, denoted as Gel/SA‐acetate) has been developed to stabilize the interfacial electrochemistry, which restructures a type of Zn 2+ ion solvent sheath optimized via a chain‐liquid synergistic effect. New hydrogen bonds are reconstructed with water molecules by the zincophilic functional groups, and directional migration of hydrated Zn 2+ ions is therefore induced. Concomitantly, the robust chemical bonding of such…
