Abstract:
Potassium single cation ionic liquid (SCIL) electrolytes, comprising a combination of potassium molten salts, have garnered interest as an alternative to highly flammable organic solvents. However, the expense of lowering eutectic temperatures and precisely determining eutectic composition in multinary SCILs is prohibitive, confining the investigation to the binary system. In this study, with the assistance of Bayesian optimization, a ternary eutectic composition is efficiently identified to successfully expand the operating temperature range: the ternary SCIL, KFSI0.31TFSI0.25TFA0.44, exhibits a low melting point at approximately 43 °C and can maintain a supercooled liquid state over 3 months at room temperature, whereas the introduction of strong Lewis base TFA- increased the cation-anion Coulombic interactions, causing a decrease in conductivity compared to the binary SCIL.
