Nb-based tungsten bronze oxides have emerged as attractive materials in various fields, owing to the structural openings and simple synthesis method. In this work, the tetragonal tungsten bronze (TTB) NaWNbO6 was prepared by solid state reaction at a relatively low temperature of 775 degrees C. The local structure was systematically studied by solid state nuclear magnetic resonance (SSNMR) with the aid of transition electronic microscopy (TEM). The analysis indicates that NaWNbO6 has pentagonal, square, and triangular tunnels. Notably, square tunnels were partly occupied (50%) by Na, which creates the ability for the li-ion storage with a volumetric capacity of 210 Ale dot>hle dot>l-1 at 0.2 C. The 2D Na-23-Na-23 EXSY results further suggest the ability of ions to fast exchange between the tetragonal and pentagonal tunnels, resulting in a high-rate performance 20 C.
