摘要：

Two approaches for in situ FTIR measurements of active and noble metal surfaces in Li battery electrolytes (propylene carbonate, ethers, and gamma-butyrolactone and Li salts) have been developed. Both methods are based on internal reflectance spectroscopy with working electrodes of thin noble metal films deposited on ZnSe or NaCl crystals. Thus the study of surface films formed on the active surfaces at low potentials in solutions and their potential dependent stability is fostered, while the masking effect of strong solution IR bands is mostly eliminated.
