The possibilities of using of anthracite-derived porous carbon material as an electrode of lithium power sources are investigated in the work by the methods of galvanostatic discharge and cyclic voltammetry. It is established that the maximum value of the specific capacity of the power source of 1440 mA·h/g is achieved when using a material with a maximum surface area (990 m2/g) and a total pore volume (0.59 cm3/g). Processes occurring in the electrochemical system Li|LiBF4 (g-butyrolactone)|C are related to the irreversible formation of a solid-state layer on the surface of carbon particles and the reversible formation of non-stoichiometric insertion phases LixC.
