▎ 摘　　要

NOVELTY - Invention relates to chemical current sources, namely to composition and structure of anode active material for lithium-ion batteries. Powder material has a core-shell structure and consists of silicon nanoparticles coated with a reduced graphene oxide shell. USE - Chemistry. ADVANTAGE - High electronic and ionic conductivity of material, high specific capacity, as well as increased stability and number of cycles due to prevention of silicon contact with liquid electrolyte and formation of bonds between separate particles of powder in electrode. 4 cl, 2 dwg, 1 ex
