The study of ionic conduction and structures in which it can be realized is very important for the development of modern batteries. Using of new materials will enable to get rid of such deficiencies as little time of life, small energy and possibility of electrolytic solution leak from battery. In this paper we present the results of study of ionic conduction process of boron and carbon (6,0) nanotubes of type BCn, n=3. Two types of relative position of boron and carbon atoms in nanotube are considered. The research was performed using the MNDO method within the framework of molecular cluster model. For the study of ionic conduction process the vacancy formation has been modeled. Energetic and electronic characteristics of these processes are defined. It has been proved that the method of defect formation on the surface of A nanotubes is the most probable. So our further researches have been carried out only for BC3 nanotubes. The vacancy migration process has been modeled. The dependence of conduction coefficient on temperature is determined.
