METHOD TO PRODUCE NANOSTRUCTURED MULTILAYER 3D COMPOSITE MATERIAL FOR NEGATIVE ELECTRODE OF LITHIUM-ION BATTERY, COMPOSITE MATERIAL, NEGATIVE ELECTRODE AND LITHIUM-ION BATTERY

摘要

FIELD: electricity. ^ SUBSTANCE: at the first stage of the method realisation on a current-conducting substrate by a method of plasma-chemical synthesis from a gas phase in a plasma of an electric DC charge, a layer of a film of a nanocrystalline graphite is formed in the form of a 3D nanocarbon structure, and on the second stage a 3D composite material is formed, for this purpose the film grown on the first stage is conformally coated with at least one layer of active anode material, such as a silicon-containing material applied above the film in an even layer with thickness of 0.03-0.5 mcm. ^ EFFECT: method simplicity, stable operation of a negative electrode of a lithium-ion battery, improved operational properties. ^ 12 cl, 7 dwg
