Rezumat

Iron sulfides were codeposited with different nature graphite for the increase of the utilization efficacy in their electrochemical reaction with lithium. Synthesized iron sulfide graphite composites have been investigated in the galvanostatic mode using a model lithium accumulator filled with an electrolyte solution of 1 M LiClO4 in EC, DMC. It was established that the codeposition of iron sulfides with synthetic graphite stabilizes the discharge capacity of electrolytic iron sulfides at their long cycling. Synthesized iron sulfide composites with synthetic graphite represent prospective negative electrodes for thin layer lithium ion batteries. The natural graphite manufactured by the Superior Graphite Company (purified surface coated natural graphite, ABG 1005, ABG 1010, formula BT SLC 1520 P) displays an unfit stabilization ability of the iron sulfide discharge capacity.
