V₂O₅/Mesoporous Carbon Composite as a cathode material for lithium-ion batteries

Abstract

V(2)O(5)/mesoporous carbon composite has been prepared by an ultrasonically assisted method followed by a sintering process. The as-prepared V(2)O(5)/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 V(2)O(5) nanoparticles. The improved electrochemical performance indicates that the V(2)O(5)/mesoporous carbon composite could be used as a promising cathode material for lithium ion batteries.
