摘要：
(NH4)(2)V3O8 microflowers were synthesized through a non-hydrothermal/solvothermal method. And 3D hierarchical (NH4)(2)V3O8 as precursor could be easily transformed into V2O5 with preserved microstructure via subsequent calcination. The thickness of nanosheets (petals) can be controlled by varying the ratio of ethanol/water in the deposition system. 3D hierarchical V2O5 flowers demonstrate a very high capacity (289 mA h g(-1)) and good cyclic stability.
