We propose a new direct anodic electrodeposition process for carbon coatings that is possible at room temperature in ionic liquid (IL) with phenylsilane derivatives, which include dimethylphenylsilane (DMPh-Si), methyldiphenylsilane (MDPh-Si), and triphenylsilane (TriPh-Si). Amongst them, MDPh-Si was found to most efficiently result in the electrodeposition of graphite carbon films even within the electrochemical window of IL. Electrochemical redox performance of Li+/Li couple on the obtained carbon film electrodes is also discussed.
