Schematic showing Li-ion migration into T -Nb 2 O 5 . The black, red and green spheres denote Nb, O and Li ions, respectively. The grey and navy polyhedra denote distorted octahedra (NbO 6 ) and pentagonal bipyramids (NbO 7 ), respectively. The grey and yellow planes represent the 4 h and 4 g layers, respectively. The loosely packed 2D 4 g layer provides for fast Li-ion transport.
