Abstract
We developed in situ FTIR and AFM measurements for the analysis of int erfacial phenomena between electrode and the organic electrolytes. Two methods of FTIR measurements, IRAS and DMFTIR were conducted for the analysis of interface between Cu electrode and EC-based electrolytes. The IRAS spectra indicate changes of the species mainly occur in the b ulk phase, while the DMFTIR spectra indicated changes of the surface s pecies mainly occur at the electrode. It was found that the solvent is reduced into various products both in IRAS spectra and in DMFTIR spec tra. Cu electrode was found to have morphologically changed into small particles at the first cathodic polarization in AFM measurements.
