Breaking the Ice: Hofmeister Effect‐Inspired Hydrogen Bond Network Reconstruction in Hydrogel Electrolytes for High‐Performance Zinc‐Ion Batteries

Gel electrolytes have emerged as a promising solution for enhancing the performance of zinc-ion batteries (ZIBs), particularly in flexible devices. However, they face challenges such as low-temperature inefficiency, constrained ionic conductivity, and poor mechanical strength. To address these issues, this study presents a novel PAMCD gel electrolyte with tunable freezing point and mechanical properties for ZIBs, blending the high ionic conductivity of polyacrylamide with the anion interaction capability of β-cyclodextrin. Leveraging the Hofmeister effect, the chaotropic anions of ClO
