METHOD OF PRODUCING ANODE MATERIALS BASED ON INCLUSION COMPOUNDS OF LITHIUM IN GRAPHITE REFINING FOAM FOR LITHIUM-ION BATTERIES Russian patent published in 2016 - IPC H01M10/52 H01M4/587 H01M4/1393 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing capacity anode materials based on compounds of activation of kish graphitic lithium and production of negative electrode for lithium-ion batteries. Graphite materials are produced at sedimentation of excess carbon contained in supersaturated solutions of carbon in iron/steel, not modified or modified banding metals/metalloids separately or in combination. According to method shape of carbon used to dissolve represents carbon-containing polymer carbon precursor, such as biomaterials and plastic wastes, which are not biodegradable, carbonisation which may be carried out in situ, or before adding to melt. Graphite products show reversible capacitance in range from 300 to 600 mA·h·g^-1, with flat profiles voltages for electrochemical switching on/lithium extraction at potential less than 200 mV.

EFFECT: increasing capacity of lithium-ion batteries is technical result of invention.
