Ethyl acetate (EA) shows low viscosity for its relative permittivity. Monofluorinated solvents exert the polar effect on the physical and electrochemical properties. Relative permittivity of 2-fluoroethyl acetate (2FEA) was lower than that of ethyl fluoroacetate (EFA), though viscosity of 2FEA was higher. Ionic conductivity of 2FEA was lower than that of EFA, but higher than that of EA at high temperatures. The anodic stability of 2FEA and EFA was higher than that of EA. The use of 2FEA as a co-solvent improved cycling efficiency of a lithium anode.
