Revealing the miscibility chemistry of ionic liquids in water-in-salt electrolytes toward high-voltage and high-temperature aqueous potassium-ion supercapacitors
A ternary water-salt-ionic liquid aqueous electrolyte was prepared by mixing hydrophobic ionic liquid EMIMNTf 2 , KOTf and H 2 O. OTf anions have a solubilizing effect on EMIMNTf 2 which is originally immiscible with H 2 O. Meanwhile, the primary solvation shell of K + is regulated by NTf 2 anions, thus enabling a supercapacitor with high-voltage and high-temperature properties.
