Evaluation of Composite Helices Used as Anodes for Rechargeable Lithium Ion Batteries
The SEM analyses demonstrated that during the co-evaporation an increase in Cu/Si atomic ratio decreased the thickness of the helices, increased the tilting angle and decreased the homogeneity in the thin film morphology. The best performance was achieved when 20%at. Cu containing SiCu helical shaped thin film is used as anode material.
