It is experimentally proved, that electrochemical properties of foamgraphite are determined by a mode of the first cycle of a charge (a mode of formation of a superficial layer on carbon). It is shown, that the mode of a charge with application of high density of a current (a mode of short circuit) creates conditions of formation superficial isolation multifunctional layer (IML) on a carbon material mainly from a carbonate of lithium. Application a mode of a charge at short circuit of electrodes on high resistance (100-200 kOm) results in formation of a superficial layer of mainly organic structure. Cycling of electrochemical cells with electrodes the charged various methods has shown, that the organic IML is supplemented a carbonate, that provides long cycling electrodes in a convertible mode with irreversible loss of capacity not above 5%. Thus the size x in intercalate LixCl6, depends on density of a cycling current, and lays in an interval from 0.3 up to 0.6. at low density of a current (about 1-10 mA/g) reaches x = 1.
