Abstract

The orthorhombic layer structured vanadium oxide, V₂O₅, is an attractive material for many essential applications. Here, a series of vanadium pentoxide micro-/nanostructures were prepared via a simple solvothermal approach followed by an annealing process. Various morphological structures from core–shell microspheres, nanosheets, hierarchical microflowers to octahedron structures can be tuned by simply changing the solvent ratio among dimethylformamide (DMF), isopropyl alcohol (IPA) and acetic acid. V₂O₅ microflowers and octahedra were investigated as cathodes for LIBs and showed good cycling stabilities and excellent ultrahigh rate capabilities.
