Abstract
The article includes the developed methods of natural graphite modification for its effective use as a cathode material of lithium power sources. It was determined that nanohybridization of thermally expanded graphite with organic thiourea increases the energy capacity Li + - intercalation galvanic reaction. This paper analyzes in detail the structure of the modified graphite and its physical properties. In particular, by small-angle X-ray scattering method, it was revealed that in the oxidized graphite the invariant Species is significantly lower than the same parameter for graphite bisulfate. This depends on a decrease of the scattering approximately by 5 times on electronic inhomogeneities. The heat treatment of graphite bisulfate at 600 and 800 о С increases the poral volume by about 4 times. For the first time, the supramolecular ensemble of mesoporous graphite – ferrocene was synthesized, as an active material for pseudocapacitors, which provides the increase of the specific capacity of initial activated carbon
