Preparation of Boron Doped Fullerene Film by a Thermal Evaporation Technique using Argon Plasma Treatment and Its Electrochemical Application Arie, Arenst Andreas; Jeon, Bup-Ju; Lee, Joong-Kee;
Boron doped fullerene () films were prepared by the thermal evaporation of powder using argon plasma treatment. The morphology and structural characteristics of the thin films were investigated by scanning electron microscope (SEM), Fourier transform infra-red spectroscopy (FTIR) and x-ray photo electron spectroscopy (XPS). The electrochemical application of the boron doped fullerene film as a coating layer for silicon anodes in lithium ion batteries was also investigated. Cyclic voltammetry (CV) measurements were applied to the coated silicon electrodes at a scan rate of . The CV results show that the coating layer act as a passivation layer with respect to the insertion and extraction of lithium ions into the silicon film electrode.
