Among the existing cathode materials,V2O5 is a promising cathode candidate because of its high energy density,abundance,easy synthesis,as well as low cost.However,due to quite low diffusion coefficient of lithium ions (10-12-10-13 cm2 s-1),irreversible phase transitions during deep discharge,and vanadium dissolution into the electrolyte,the practical use of V2O5 as a cathode material shows poor rate capability and cycling stability1,2.
