Abstract

A facile synthesis of novel 3D porous V₂O₅ hierarchical microspheres has been developed, based on an additive-free solvothermal method and subsequent calcination. Due to their unique structure, these V₂O₅ microspheres display a very stable capacity retention of 130 mA h g^-1 over 100 cycles at a current rate of 0.5 C, and show excellent rate capability with a capacity of 105 mA h g^-1 even at the 30 C rate. The good electrochemical performance suggests that this unique hierarchical V₂O₅ material could be a promising candidate as a cathode material for lithium-ion batteries. © 2013 The Royal Society of Chemistry.
