摘要：

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 (similar to 25 mS cm(-1) at 20 degrees 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.
