Abstract

Anatase TiO₂ nanocrystals doped with nitrogen and sulfur, where substitutional N and S atoms for lattice O, respectively, locate in the bulk and the surface layer of the crystals, were designed and prepared. As a result of remarkably lowered electronic resistance, the N/S doped TiO₂ shows a superior high rate lithium storage capability to that of reference TiO₂ nanocrystals, though the former has a larger particle size.
