Abstract
Abstract Flexible ionic conductors hold potential for wearable sensors and energy harvesting. However, most gel‐based conductors suffer from solvent evaporation and liquid leakage, limiting practical applications. Although solid‐state ionic conductors mitigate these issues, achieving strong mechanics, high conductivity, self‐healing, and stability remains challenging. Here, by integrating supramolecular engineering and dynamic covalent adaptive networks, a self‐healing polyurethane‐based solid‐state ion‐conductive elastomer (DACPU/100Li) with outstanding overall properties is successfully synthesized. DACPU/100Li exhibits ultrahigh ionic conductivity (1.23 × 10 − 3 S cm −1 ) and high tensile strength (7.62…
