Abstract: A new type of 3-D flower-like monoclinic sodium ammonium vanadium bronze nano-architecture consisting of single crystalline nano-platelets was prepared. Under the hydrothermal condition, the intercalation of two kinds of cations (such as Na+ and ) induced structural transformations of the vanadium bronzes and gave rise to novel crystalline structures with specific morphologies. When used as positive electrode materials in rechargeable lithium battery, this sodium ammonium vanadium bronze exhibited high discharge capacity of ca. 200mAhg−1 in the range of 2–3.4V and excellent cycle stability.
