Synthesis and Electrochemical Behavior of Carbon Alloy C x N

Abstract
CxN compounds were coated on two kind of graphites, natural graphite treated with 94%HN03 solution and the natural graphite without treatment, by chemical vapor deposition. XPS and Raman spectroscopy revealed that these materials were not mixtures of CxN and graphites, but CxN coated-graphites. As anodes of secondary lithium battery, the CxN-coated graphites demonstrated the higher capacity than that of natural graphite, good cycleability, and gradual increase in the potential at the last stage of lithium deintercalation reaction.
