LITHIUM-ION BATTERY BASED ON A MULTILAYERED THREE-DIMENSIONAL NANOSTRUCTURED MATERIAL

摘要

The group of inventions relates to the chemical and electrical engineering industries. The technical result consists in the possibility of using a simple method to produce a material which has optimum parameters and high use qualities, and which ensures operational stability of the negative electrode of a lithium-ion battery based on such a material. In the first step for implementing the method, a layer of a film of nanocrystalline graphite in the form of a three-dimensional nanocarbon structure is formed on a current-conducting substrate using the procedure of plasmochemical synthesis from the gaseous phase in the plasma of a direct current electrical charge. In the second step, a three-dimensional composite material is formed, for which the film grown in the first step is covered conformally with at least one layer of active anode material, with the active anode material used being a silicon-containing material which is applied on top of the film with a uniform layer thickness of 0.03-0.5 μm. What is characterized is: a nanostructured three-dimensional composite material, a negative electrode of a lithium-ion rechargeable battery and such a battery.
