Abstracts

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.
