Abstract Unstable interphase formed in conventional carbonate‐based electrolytes significantly hinders the widespread application of lithium metal batteries (LMBs) with high‐capacity nickel‐rich layered oxides (e.g., LiNi 0.8 Co 0.1 Mn O 2 , NCM811) over a wide temperature range. To balance ion transport kinetics and interfacial stability range, herein bifunctional electrolyte (EAFP) tailoring electrode/electrolyte 1,3‐propanesultone as an additive was developed. The resulting cathode‐electrolyte inorganic inner layer organic outer possesses high mechanical flexibility, alleviating stress accumulation maintaining structural integrity NCM811 cathode. Meanwhile, inorganic‐rich solid inhibits side reactions facilitates fast Li + transport. As result, Li||Li cells exhibit stable performance extensive temperatures low overpotentials, especially achieving long lifespan 1000 h at 30 °C. Furthermore, optimized EAFP is also suitable for LiFePO 4 LiCO cathodes (1000 cycles, retention: 67 %).
