摘要：Herein, we report the synthesis of orthorhombic V2O5array with hair-like, javelin-like and wall-like structures on conductive titanium foil by a simple time-dependent hydrothermal method. The morphological evolution process of this product has been investigated in detail. The affection of morphology on sodium storage performance is probed. Benefitting from the unique javelin-like structure, the orthorhombic V2O5array shows a prolonged cycle ability and high rate ability. Ex-Situ scanning electron microscope (SEM) and electrochemical impedance spectroscopy (EIS) are performed to clarify the mechanism.
