Iron sulfides were codeposited with different nature’s graphite for the increase of utilization efficacy theirs in electrochemical reaction with lithium. Synthesized iron sulfide-graphite composites have been investigated by galvanostatic mode using lithium accumulator model which were 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 theirs long cycling. Synthesized iron sulfide composites with synthetic graphite present the perspective as negative electrodes for thinlayer lithium-ion batteries. Natural graphite’s manufactured by Superior Graphite Company (Purified Natural Graphite Surface Coated, ABG 1005, ABG 1010, Formula ВТ SLC 1520 Р) display unfit stabilizator ability of iron sulfide discharge capacity.
