The aim of this thesis is to present the application of fullerene C60 thin film as a novel coating material for Si film anodes of lithium ion secondary batteries. Fullerene C60 film is prepared and synthesized by plasma assisted thermal evaporation technique. The thesis firstly focuses on the structural and electrochemical characteristics of C60 coated Si anodes. The estimation of Li-ion diffusion coefficients in the coated Si anodes is the second topic investigated. Finally, the thesis discusses about the effect of coating layer thickness especially on the electrochemical characteristics of C60 coated Si anodes.
