Rational construction and decoration of Fe0.5Nb24.5O62−x@C nanowires as superior anode material for lithium storage

Niobium-based oxides have recently attracted great attention as anode material for lithium ion batteries (LIBs) because of high theoretical capacity, high working potential and outstanding rate performance. Nevertheless, the practical capacity of niobium-based oxides still cannot meet the demand for electrical energy storage applications in electric vehicles for low conductivity and poor ion transfer. Here, the Fe0.5Nb24.5O62−x@C nanowires are...
