XRD-analysis (DRON-2.0), optical microscopy (Оptical microscope NU-2 Carl Zeiss),electrochemical investigation by galvanostatic mode and cycling CV (VoltaLab PJZ 301).It was shown that individual sulfide positive abilities combine in synthesized binarny metal-sulfide compounds.The increase of sulfide discharge characteristics may be attained by the modification of material morphology and its structure as well as by the adhesion increase of active material to subsrate.The increase adhesion abillity of sulfide compounds have been promoted by their codeposition with grafite. It was shown the dependence of binary sulfide structure and its electrochemical characteristics in the reaction with lithium on electrolysis conditions, substrate nature. It was proposed the mechanism of electrolytic sulfide formation. It was established that sulfide formation at current density of 1-5 mА/сm2 carried out with insignificant polarisation and about 100% current rear; the favourable synthesis conditions were defined for binary sulfide with optimal structure and discharge capacity about 600 mА•h/g. Binary Со, Ni-sulfides present as perspective materials for negative electrodes lithium-ion systems.The 2-Volt lithium-ion system in the basis of such cathode material as LiMn2O4, LiCoO2 and one negative eletrode material as electrolytic binary Со, Ni-sulfide was proposed. Using fields: chemical power sources for electrotechnical,electronical, medicine and light industry.
