- Opis:
- 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.
