Improving the electrochemical properties of carbon anodes in lithium secondary batteries
The electrochemical properties of carbon anodes in lithium secondary batteries an improved by the addition of vanadium as V2O5. The action of the added V2O5 is different from that obtained by incorporating a nonmetallic element such as nitrogen, boron, phosphorous or silicon. Because it can increase the distance between the 002 planes of the carbon and act as nucleating agent that promotes the formation of a layer-like carbon structure, V2O5, not only enlarges the carbon anode's reversible capacity of lithium storage but also improves the cycling behavior.
