The work aim is the surface modelling of the electrolyte/ solid state binary metalsufide. The result generelization of the theoretical bases and the experimental researchs at the model lithium accumulators on the base of the electrolytic binary metalsulfides was provided.Research methods and apparatus - XRD-analysis (DRON-2.0); оptical spectroscopy (Оptical microscope NU-2); electrochemical investigations by galvanostatic mode; cycling voltammetry, electrochemical impedance spectroscopy (VoltaLab PJZ 301). The determination of the conformity to natural laws of the electrochemical discharge/charge of the electrolytic binary e-2-Me-sulfide /Li system was determinated the key role of the surface film formation at the activ electrode material, and also the role of the charge transfer resistance throuth surface electrode/electrolyte in alkylcarbonate electrolyte. In the aspects of the electrolytic sulfide synthesis of the transition metals the role of the electrolyte agitation have been established, the positive effect of the electrolyte agitation is determined on the composition and stabilization of the discharge-charge processis of the sulfide material at cycling in model lithium accumulator, and also on its energetic characteristics. The results of the theoretical and experimental investigations in model Li accumulator on the base of electrolytic binary metalsulfide test on the dependance of the electrolyte nature and composition have been summarized; conclution and recomendations on the base of the work results have been formulated.
