Here, we report an aqueous/nonaqueous hybrid electrolyte based on sodium trifluoromethanesulfonate with an expanded electrochemical window up to 2.8 V and high conductivity (∼25 mS cm^–1 at 20 °C). The hybrid electrolyte inherits the safety characteristic of aqueous electrolytes and the electrochemical stability of nonaqueous systems, enabling stable and reversible operation of the Na₃V₂(PO₄)₃/NaTi₂(PO₄)₃ sodium-ion battery.

钠离子电池水/非水混合电解质

在这里，我们报告了基于三氟甲磺酸钠的水/非水混合电解质，电化学窗口扩展至2.8 V，具有高电导率（在20°C时约为25 mS cm ^–1）。混合电解质继承了水性电解质的安全特性和非水体系的电化学稳定性，从而使Na ₃ V ₂（PO ₄）₃ / NaTi ₂（PO ₄）₃钠离子电池稳定且可逆地运行。
