摘要Abstract: Various morphologies of vanadium pentoxide (V2O5) have been synthesized via a facile, eco-friendly, bottom-up and self-assembly approach using hydrothermal process at low temperature with a very high-yield for the first time. The as-prepared V2O5 plate-like structure shows excellent lithium storage and rate capability compared to its tube-like structure and commercial V2O5 powder. The specific capacity of V2O5 plate can reach 470 mAhg-1 at the first cycle with a current density, 17mAg-1 (about 0.05C) and 120 mAhg-1 at high current density, 1360 mAg-1 (about 13C).
