ANODE FOR ACCUMULATOR OF LITHIUM-ION BATTERY, METHOD OF ITS MANUFACTURING AND BATTERY CONTAINING IT Russian patent published in 2017 - IPC H01M4/04 H01M4/137 H01M10/561 

FIELD: electricity.

SUBSTANCE: anode, used in the accumulator of lithium-ion battery, comprises electrolyte based on lithium salt and a nonaqueous solvent, to the method of the anode manufacturing and to the lithium-ion battery with one or more accumulators, which include the anode. This anode is based on a polymer composition obtained by melt processing and without evaporation of the solvent, whereas the composition is the product of the reaction of hot compounding between the active material and additives containing a polymeric binder and electroconductive filler. According to the invention the binder is based on at least one cross-linked elastomer and the additives also comprise at least one non-volatile organic compound used in the electrolyte solvent, wherein the composition mainly contains the mentioned active material in a mass fraction greater than or equal to 85%.

EFFECT: increased efficiency of lithium-ion batteries using a polymer anode composition, improved safety and environmental performance using a cross-linked composition.
