“…21,22 But, as a wide band gap semiconductor (∼3.2 eV), the low electronic conductivity (<10 −9 S cm −1 ) of TiNb 2 O 7 is a significant shortcoming. 23,24 To mitigate this drawback and enhance the Li storage kinetics, various structural engineering approaches have been attempted. Specifically, decreasing the particle size, carbon coating, or producing complex porous nanostructures lead to improved conductivity and Li-ion transport.…”
