Figure 6. First two-cycle (A) pristine and (B) two-dimensional in-situ XRD patterns of Nb4W7O31/Li in-situ cell with corresponding discharge/charge curves within 3.0-0.8 V at 0.3C (
: PE preservative film; 
: WO3). (C) Variations in lattice constants of Nb4W7O31. Ex-situ HRTEM images of (D) pristine (OCV), (E) lithiated (0.8 V), and (F) delithiated (3.0 V) Nb4W7O31 samples.
