Electrochemical intercalation of lithium or perchlorate ion into graphite-like layered material of BC6N

The material of composition BC6N with high crystallinity has been synthesiz ed by CVD reaction of BCl3 with acrylonitrile at 1500-2000 degrees C. BC6N electrode has shown opposite electrochemical behavior to graphite electrode in the several electrolyte. Comparison of the open circuit potentials at t he initial stage for the intercalation of lithium suggests that the conduct ion band of BC6N could be more antibonding than that of graphite. On the ot her hand, the electrochemical intercalation of perchlorate suggests that th e highest levels of the valence bands are not so different for both BC6N an d graphite The band gap of BC6N could be estimated to be 1.7eV by this elec trochemical method.
