Zusammenfassung:Herein, (NH 4 ) 2 V 7 O 16 hierarchical structures formed by the self-assembly of nanoflakes were successfully synthesized by a one-step rotating hydrothermal method. When utilized as anodic materials for aqueous Li-ion batteries, the obtained (NH 4 ) 2 V 7 O 16 exhibited good rate capability and excellent cyclic stability. Moreover, the structural evolution of the ammonium vanadium bronze during cycling was also investigated by ex situ XRD.
