초록
Carbonaceous thin films were prepared from acetylene and argon gases by plasma assisted chemical vapor deposition (Plasma CVD) at 873 K. The carbonaceous thin films were characterized by mainly Raman spectroscopy, and their electrochemical properties were studied by cyclic voltammetry and charge-discharge measurements in propylene carbonate (PC) solution. Raman spectra showed that crystallinity of carbonaceous thin films is correlated by the applied RF power. The difference of the applied RF power also affected on the results of cyclic voltammetry and charge-discharge measurements. In PC solution, intercalation and de-intercalation of lithium ion can occur as well as in the mixed solution of EC and DEC.
