KINETICS OF FORMATION PROCESS OF COMPOUNDS OF LITHIUM INTRODUCTION INTO GRAPHITE
Analysis of electrochemical tests of lithium-ion battery models using negative electrode of different carbon materials as material was done. Calculations of diffusion-kinetic parameters of the introduction process of lithium into the structure of the carbon material were done using potentialstatic 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 diffusion-kinetic parameters of the processes running at Kureiskoyoe 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.
