Abstract The thermal effect crisis poses a significant challenge to large‐scale application of energy storage devices. Hydrogel electrolytes are regarded as promising substrates for these applications due the ionic conductivity and safety. This work presents quasi‐solid‐state electrolyte with dual insurance mechanism based on unique structural, designed long‐term safe operation first protection involves microspheres embedded in matrix hydrogel network, which initiate dual‐linkage accelerate hydrophilic‐to‐hydrophobic state transition response heat accumulation. process rapidly closes ion transport channels. Complementing this mechanism, water evaporation further impedes migration, forming second insurance. Due reversibility device's initial capacity can be restored upon cooling. Moreover, regenerative behavior dynamically regulates matrix's content, ensuring recovery capacity. Theoretical simulations experiments demonstrate that offers broad tunable temperature range. Notably, thermally reversible repeated multiple times without compromising electrochemical performance, facilitating autonomous operation. prepared hydrogels also self‐healing capabilities mechanical flexibility, thereby enhancing durability self‐heating protected
