To determine the reasons of the difference between the parameters of lithium intercalation process for materials of the same nature, the nanodispersed TiO_{2} was synthesized by pyrogenic method from TiCl_{4} in hydrogen-air flame with SiCl_{4} doping precursor and was compared with TiO_{2} of "Merck" quality. The X-ray analysis with the use of small-angle scattering method, electronic scanning microscopy and impedance spectroscopy were used to determine aforesaid parameters. Obtained results show that the reason of such behaviour lays in size effect and in modification of energetic topology of impurity system. Thermodynamic parameters of intercalation reaction agree well with investigated properties of ceramic samples.
