Concentrated potassium acetate as a water-in-salt electrolyte provides a wide potential window from −1.7 to 1.5 V vs Ag/AgCl_KCl sat.. It facilitates the reversible operation of KTi₂(PO₄)₃, an anode of potassium-ion batteries, that otherwise only functions in nonaqueous electrolytes.

钾离子电池的盐包水电解质

相对于Ag / AgCl _KCl饱和溶液，浓盐乙酸钾作为盐包水型电解质提供了-1.7至1.5 V的宽电位窗口_。。它有利于钾离子电池的阳极KTi ₂（PO ₄）₃的可逆操作，否则它仅在非水电解质中起作用。
