OPPORTUNITIES FOR THE USIHG OF DOMESTIC NATURAL GRAPHITE FOR MANUFACTURING OF LIQUID-ION BATTERIES

Abstract

The purpose of this work was to introduce some physical characteristics of special commercial graphites and to study the properties of a number graphites of the Zavallevsky plant.  The  structure  of  the  samples  was  studied  using  optical  and  scanning  electron microscopy  with  an  X-ray  fluorescence  analyzer.  The  fractional  composition  of  graphite  was  determined
using  fractional  sieves,  photographic  and  photo-sedimentation  methods.  The  electrical  conductivity  was measured by a four-electrode method. Electrochemical characteristics were determined by the impedance method and the cyclic voltamperometry method. Results. A comparative analysis of special graphite natural graphites of a number of commercial firms and graphite of the Zavallievsky plant. Based on this analysis, graphite from the EUZ-M brand was chosen from domestic graphites for electrochemical studies.  Originality.  Electrochemical  properties  of  electrodes  with  this  graphite  are  similar  to  electrodes with commercial graphites. Practical value. Domestic graphite, first of all graphite EUZ-M, after additional purification has the prospect of successful use in the production of electrodes LIA.
