Opis:: A microwave-intercalation modification of natural graphite which ensures its effective use as a cathode material of Li-based sources of electric current is developed. Interconnection between the parameters of modification and thermodynamic and kinetic behavior of Li-intercalation electric current generation is established. On the basis of the obtained data from impedance spectroscopy, X-ray diffractometry analysis, and spectroscopy of the Raman scattering of light, the mechanism of the observed phenomena is suggested.

Opis:: Results of the dielectric relaxation studies, performed for supramolecular polymer formed by N,N'-di(2,2-dipentylheptyl)urea dissolved in carbon tetrachloride, are presented. The measurements were done for N,N'-di(2,2-dipentylheptyl)urea concentration up to about 7% (in mole fraction) in the frequency region from 100 kHz to 100 MHz and at the temperatures from 5ºC to 50ºC. The analysis of the experimental data were performed with the Havriliak-Negami equation. In the studied range of N,N'-di(2,2-dipentylheptyl)urea concentration and temperature, the obtained values of exponentsα andβ of the Havriliak-Negami equation are equal to 0.9±0.1 and 0.7±0.1, respectively, showing an anomaly in the dielectric relaxation behavior close to the Davidson-Cole type. Two examples of the modeling of dielectric properties of the supramolecular polymer solutions were presented.
