The optimization of binary metal-sulfide/electrolyte/lithium system by electrolytic graphitization method, theoretic and experimental researches of lithium intercalation in electrolytic binary metal-sulfides by potentiostatic impulse titration method is the work aim. The investigation methods and the techniques have been used XRD-analysis (DRON-2.0), optical microscopy (optical microscope NU–2, Carl Zeiss), electrochemical investigations by galvanistatic mode and cycling voltammeter (VoltaLab PJZ 301). Aspects of binary Fe, Co- and Fe,Ni–sulfide compounds synthesis and also of binary improve mental composites by electrolytic graphitization have been investigated by the analysis of the cathode reduction of aqueous electrolytes. In the graphitization of binary metal-sulfides it was used the graphite’s of different trade-mark. The satisfactory results have been obtained with the nature graphite of GAK, EUZ-M and china trade-marks. The graphite’s promote adhesion rise of binary metal-sulfides with metal and the increase of their discharge capacity. The improvement of the discharge characteristics of the synthesized metal-sulfide compounds have been obtained by using LiBOB sol in the electrolyte of lithium accumulator model. As the result of electrolytic metal-sulfide PIT-researches it was established the conformity to natural laws that characterizes the phase transitions in include electrodes of lithium power sources. She follows from the relation of differential intercalation maxima capacity (Сdif)-E and chemical diffusion coefficient of lithium ions minima (DLi-E). On the base of the obtained results it can considered that in the intercalation of electrolytic iron sulfide at 1.5 V it is possible the phase transition with interaction between charged sites by the repulsion.
