Abstract
A unique polymerized C-60 thin film was functionalized by radio frequency - plasma-assisted thermal evaporation as a passivation layer for the fluorine-doped tin oxide (SnO2:F) anode of a lithium-ion battery. The plasma-polymerized C-60 coated SnO2:F anode exhibited a high initial discharge capacity of 1255 mAh g(-1) at 0.15 mA cm(-2) and increased coulombic efficiency of 98%. These electrochemical improvements were due to the polymerized C-60 coating layer, which enhanced the transport of lithium ions on the surface of the active material and mechanically stabilized the anode material during electrochemical cycling.
