Abstract Sodium‐ion batteries (SIBs) present a promising avenue for next‐generation grid‐scale energy storage. However, realizing all‐climate SIBs operating across wide temperature range remains challenge due to the poor electrolyte conductivity and instable electrode interphases at extreme temperatures. Here, we propose comprehensively balanced by pairing carbonates with low‐freezing‐point low‐polarity ethyl propionate solvent which enhances ion diffusion Na + ‐desolvation kinetics sub‐zero Furthermore, leverages combinatorial borate‐ nitrile‐based additive strategy facilitate uniform inorganic‐rich interphases, ensuring excellent rate performance cycle stability over from −45 °C 60 °C. Notably, Na||sodium vanadyl phosphate cell delivers remarkable capacity of 105 mAh g −1 high 2 C −25 In addition, cells exhibit cycling range, maintaining retention 84.7 % 3,000 cycles 95.1 500 cycles. The full also exhibits impressive range. This study highlights critical role interphase engineering enabling that function optimally under diverse climatic environments.

Reliable power supplies at extremely high temperatures are urgently needed to broaden the application scenarios for electric devices. Aqueous zinc metal batteries (ZMBs) with intrinsic safety a promising alterative high-temperature energy storage. However, reversibility and long-term cycling stability of aqueous ZMBs (≥100 °C) have rarely been explored. Herein, we reveal that spontaneous Zn corrosion severe electrochemical hydrogen evolution temperature vital restrictions traditional ZMBs. To address this, crowding agent, 1,5-pentanediol, was introduced into an electrolyte suppress water reactivity by strengthening O-H bonds H2O decreasing content in Zn2+ solvation sheath, while maintaining flame resistance electrolyte. Importantly, this enabled reversible deposition Coulombic efficiency 98.1% long life Zn//Zn over 500 cycles (at 1 mA cm-2 0.5 mAh cm-2) 100 °C. Moreover, stable Zn//Te full °C demonstrated.
