- •
A novel hierarchical starfish-like vanadium oxide are synthesized by a simple hydrothermal method.
- •
The functional V2O5 sol plays a crucial role for formation hierarchical starfish-like structure.
- •
Starfish-like vanadium oxide grown along the (1 1 0) plane and four oblique sheets grown on the flanking of (1 1 0) plane, respectively.
- •
Hierarchical starfish-like V2O5 cathode materials can deliver discharge capacity of approximately 163 mA h g−1 at high current density of 1000 mA g−1 (5C) after 50 cycles
