It was found that polynuclear complexes NiX2·2(fac-Co(Etm)3).], [NiX2·2[Co(Dctm)2] [NiX2·2[Co(HTetm)2], where Etm, Detm, Tetm are deprotonated molecules of mono- (NH2C2H4O) di- (NH(C2H4O)2) and tri-ethanolamine (N(C2H4O)3), after being inoculated onto the surface of graphite with subsequent pyrolysis in the inert atmosphere, become catalysts toward the reaction of Li intercalation into the graphite, thus imp
