Abstract High‐power‐density rechargeable batteries are highly indispensable for power‐intensive application scenarios, such as vehicle start‐stop system and grid‐level frequency regulation. However, realizing high‐power‐density alkali‐ion is challenging especially at low temperatures, undesirable alkali metal plating tends to occur more easily on the anode surface due increased electrochemical impedance polarization.

More importantly, enhanced contact‐ion pairs solvation structure induces an anion‐derived, thin, NaF‐rich solid interface (SEI) HC anodes with interfacial resistance ensure facile + diffusion through SEI. Consequently, assembled demonstrates record‐high power density 1132.31 W kg (with energy 61.94 Wh °C 13372.56 (132.83 25 (based total mass active materials cathode).
