Very large area, uniform TiO2@ carbon composite nanofibers were easily prepared by thermal pyrolysis and oxidization of electrospun titanium(IV) isopropoxide/polyacrylonitrile (PAN) nanofibers in argon. The composite nanostructures exhibit the unique feature of having TiO2 nanocrystals encapsulated inside a porous carbon matrix. The unique orderly-bonded nanostructure, porous characteristics, and highly conductive carbon matrix favour excellent electrochemical performance of the TiO2@ carbon nanofiber electrode. The TiO2@ carbon hybrid nanofibers exhibited highly reversible capacity of 206 mAh g(-1) up to 100 cycles at current density of 30 mA g(-1) and excellent cycling stability, indicating that the composite is a promising anode candidate for Li-ion batteries.
