Abstract Solid‐state sodium metal batteries garner significant attention due to their low cost, high safety, and remarkable energy density. However, interface instability hinders further development. Herein, an in situ polymerized electrolyte is developed incorporating a liquid alloy (LM) that simultaneously achieves ionic conductivity self‐healing interfacial stability. This of 2.7 × 10 −3 S cm −1 at room temperature. Additionally, the demonstrates capabilities because special electric field‐induced motion fluidity LM. The resulting battery enhances cycling Symmetric cells exhibit 1,900 h stability limiting current density 1.91 mA −2 temperature, demonstrating exceptional long‐term reliability. rational design strategy breakthrough quasi‐solid‐state technology while providing practical route toward commercializing high‐energy‐density storage systems.
