Despite the remarkable advances in mitigating ice formation and accretion, however, no engineered anti-icing surfaces today can durably prevent frost formation, droplet freezing, accretion an economical ecofriendly way. Herein, sustainable low-cost electrolyte hydrogel (EH) are developed by infusing salted water into a matrix for avoiding icing. The EH both ice/frost extremely long time reduce adhesion strength to ultralow value (Pa-level) at tunable temperature window down -48.4 °C. Furthermore, self-remove from tilted surface within 10 s -10 °C self-gravity. As demonstrated molecular dynamic simulations experiments, these extreme performances attributed diffusion of ions interface between ice. properties be maintained replenishing real-time with available ion sources, indicating promising applications offshore platforms ships.
