Ionic liquid “ECOENG™ 110”, a promising electrolyte for electrochemical devices, was investigated by impedance spectroscopy. Metallic electrodes (Pt, Cu, Ag, and Mo) as well as carbon were used for the electrochemical characterization. The dependences of the real and imaginary impedance, polarization resistance and electrochemical capacity of the double layer on the electrode potential were investigated using electrical equivalent circuits of R1(QR2) and R1[Q(R2W)] types.
Research highlights► We investigated Ionic liquid "ECOENGTM 110" by impedance spectroscopy. ► Metallic electrodes (Pt, Cu, Ag, and Mo) as well as carbon were used. ► We used electrical equivalent circuits of R1(QR2) and R1[Q(R2W)] types. ► The process on the carbon electrode is limited by non-faradic diffusion.
