The physical and electrochemical properties of three ionic liquids (ILs) containing an alkyl sulfate group as anions are investigated. They exhibit wide electrochemical windows of about 5.0 V, and one pyrrolidinium-containing ionic liquid shows a conductivity of 3.8 mS/cm. The various cations of alkylsulfate-containing ionic liquids are shown to greatly influence viscosity and conductivity. The electrochemical and thermal stabilities of these ILs make them promising electrolytes for use in electrochemical devices.
