Analysis of electrochemical tests of lithium-ion battery models using negative electrode of different carbon materials as material was doneand gel-polymer electrolyte. Calculations of electrochemical parameters of the introduction process of lithium into the structure of the carbon material were done using potential static and potentialdynamic methods. It is shown that the processes kinetics running on the negative electrode of lithium-ion battery is significantly affected by the nature of the carbon material. The electrochemical parameters of the processes running at Kureisky deposit graphite electrodes are shown to be comparable with those of the material CZ-50 (Nippon Carbon, Japan). It is shown that regardless of the nature of carbon material 2 processes run at first charge cycle: lithium-ion intercalation into carbon material structure and formation of the solid electrolyte interphase on its surface. A gel-polymer electrolyte secondary cell that is superior in the cycle characteristic and security during cell overcharge is provided. The gel- polymer electrolyte of the cell includes a non-aqueous solvent, a lithium salt, and a polymer (Acrylic R280, butadiene-nitrile rubber BNRS-28AMN).
