Weakly solvating electrolytes (WSE) can favor reversible Na batteries at -40 °C for some extreme applications because of the low desolvation energy. However, it is challenging to enable lower temperatures. Herein, we uncover that ionic conductivity WSE reduces reaction kinetics -60 °C.

Abstract Anode‐free sodium batteries (AFSBs) hold great promise for high‐density energy storage. However, high‐voltage AFSBs, especially those can stably cycle at a wide temperature range are challenging due to the poor electrolyte compatibility toward both cathode and anode.
