METHOD FOR OBTAINING NANOSTRUCTURED MATERIAL FOR ANODES OF METAL-ION BATTERIES Russian patent published in 2021 - IPC H01M4/36 H01M4/58 C01G39/06 B82Y40/00 

FIELD: nanotechnology and electronics.

SUBSTANCE: invention relates to the field of electronics and nanotechnology, and in particular to a method for producing nanostructured material for anodes of alkaline metal-ion batteries, in particular for lithium and sodium-ion batteries. The invention makes it possible to obtain nanostructured porous sulfides of molybdenum or vanadium, or their hybrids (VS₂/graphene material or МоS₂/graphene material), characterized by a high capacity for lithium-ion and sodium-ion batteries, which can also find application, for example, in catalysis, in sensor devices and other fields of technology. The proposed method makes it possible to simplify the production of these materials by reducing the stages, reducing the temperature and reducing the time of thermal decomposition to seconds, by thermal shock decomposition of aerogels of the starting materials or their mixture with graphite oxide at 400-700°C for 10-20 seconds in an argon atmosphere.

EFFECT: invention improves capacitive characteristics of lithium and sodium-ion batteries through the use of nanostructured material obtained by the claimed method.
