V2O5/mesoporous carbon composite as a cathode material for lithium-ion batteries

V2O5/mesoporous carbon composite has been prepared by an ultrasonically assisted method followed by

a sintering process. The as-prepared V2O5/mesoporous carbon material containing 90 wt% V2O5 shows

better electrochemical performance, with capacity of 163 mA h g-1 after 100 cycles at the current density

of 500 mA g-1, as well as better charge/discharge rate capability for lithium storage than V2O5

nanoparticles. The improved electrochemical performance indicates that the V2O5/mesoporous carbon

composite could be used as a promising cathode material for lithium ion batteries.
