Hydrogen‐Bond‐Rich Supramolecular Multiblock Copolymers Facilitate Rapid Zn2+ Migration in Quasi‐Solid‐State Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
The disordered growth of dendrites, corrosion, parasitic side reactions, slow de‐solvation kinetics, and inherent safety risks significantly hinder the practical deployment of conventional liquid electrolyte zinc‐ion batteries. In contrast, the novel PU‐EG+DMPA‐Zn polyurethane quasi‐solid‐state electrolyte, enriched with abundant polar functional ...
