| Outline of Final Research Achievements |
The compound with a composition BC2N has been prepared by chemical vapor deposition method. Sodium (Na) can be intercalated into BC2N by electrochemical method. The reversible capacity was 190 mAh/g. The interesting point was that the intercalation proceeded with the formation of stage structures. From these results, B/C/N compound will be one of the candidates of anode of Na ion batteries.
Magnesium (Mg) has been intercalated into BC2N by using a vapor phase method. This is the first example of the Mg intercalation into graphite-like layered compounds. The intercalation mechanism has been explained by the relation between the ionization potentials of metals and the electron affinities of host compounds.
