Abstract Interface instability and safety concerns related to lithium anodes are major barriers the practical use of Li‐CO 2 batteries. To address these challenges, an organic–inorganic dual‐layer protective coating is developed improve Li⁺ transport, provide electronic insulation, isolate CO H O. Deep eutectic solvents (DESs) used as electrolyte additives promote a stable, inorganic solid interphase (SEI) composed Li 3 N, LiF, LiCl, which enhance ionic conductivity, lowers surface energy, suppresses dendrite growth. Additionally, elastic Li‐Nafion buffer layer incorporated mitigate volume expansion during cycling. This dual protection system significantly improves cycling stability, extending lifespan Li||Li batteries by 5.19 4.62 times, respectively, with reversible cycle life 4160 h. A pouch battery using this also demonstrates exbatteryent 1400 h at 50 µA cm −2 cut‐off specific capacity 250 µAh . These findings offer valuable insights for enhancing stability longevity
