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.
