Highly stable and flexible Li-ion battery anodes based on TiO2 coated 3D carbon nanostructures

Abstract

Hierarchical three-dimensional carbon nanowire arrays on carbon cloth have been developed as an efficient flexible nanostructure current collector for TiO₂ based anodes. This unique electrode exhibits not only ∼300 times higher mass loading than that of 2D planar substrates, but also high reversible capacity, remarkable rate capability and cycling stability (up to 8000 cycles).
