Abstract Quasi‐solid‐state aqueous zinc ion batteries suffer from anodic dendrite growth during plating/stripping processes, impeding their commercial application. The inhibition of dendrites by high‐modulus electrolytes has been proven to be effective. However, hydrogel are difficult achieve high modulus owing inherent water contents. This work reports a electrolyte with ultrahigh that can overcome the stress through mechanical suppression effect. By combining wet‐annealing, solvent‐exchange, and salting‐out processes tuning hydrophobic crystalline domains, is obtained substantial content (≈70%), (198.5 MPa), toughness (274.3 MJ m −3 ), zinc‐ion conductivity (28.9 mS cm −1 which significantly outperforms previously reported poly(vinyl alcohol)‐based hydrogels. As result, exhibits excellent dendrite‐suppression effect achieves stable performance in Zn||Zn symmetric (1800 h cycle life at 1 mA −2 ). Moreover, Zn||V 2 O 5 pouch display cycling operate stably even under extreme conditions, such as large bending angle (180°) automotive crushing. provides promising approach for designing mechanically reliable advanced batteries.
