Molecular Bridging Induced Anti‐Salting‐Out Effect Enabling High Ionic Conductive ZnSO4‐Based Hydrogel for Quasi‐Solid‐State Zinc Ion Batteries

full battery maintains a remarkable Coulombic efficiency (>99.7 %) even after 8000 cycles. The anti-salting-out strategy proposed in this work provides an insightful concept for addressing the phase separation issue of functional HEs.
