Abstract: Khaki-coloured niobium oxides (H-Nb₂O₅) nanochains were synthesised via a facile low temperature solution-based method combined with hydrogenation treatment process. The nano-sized chain-like architectures facilitate the fast lithium ion diffusions. Meanwhile, the hydrogen reduction process can effectively endow Nb₂O₅ with partial Nb⁴⁺ species and/or oxygen vacancies, resulting in a large enhancement of its intrinsic electronic conductivity. When evaluated for lithium storage capacity, the H-Nb₂O₅ showed twice the rate capability at 20 C compared to that of the pristine Nb₂O₅ nanochains due to the combination of the reduced path and Nb⁴⁺ doping induced high electronic conductivity. This facile hydrogenation method is promising for designing high performance carbon-free electrode materials for lithium ion batteries.
