Electrochemical properties of carbon-coated TiO2 nanotubes as a lithium battery anode material

► Carbon-coated TiO2 nanotubes are prepared by sol-gel mixing with poly(vinyl pyrrolidone). ► The poly(vinyl pyrrolidone) component forms partially crystalline carbon layer. ► The carbon layer allows an excellent cycle performance and high-rate capability for lithium-ion batteries.
