▎ 摘　　要

NOVELTY - Lithium-ion battery containing silicon cathode, comprises an anode sheet and a cathode sheet, where the active material of cathode sheet is a composite of silicon oxide, cathode graphite, single-wall carbon tube, conductive carbon black, and graphene oxide in a mass ratio of 5:93:0.3:0.5:0.2. In the cathode material, the mass ratio of cathode active material, CMC and SBR is 96.8-97: 8:0.8-1: 6:1-2. The shell of the lithium-ion battery package is an aluminum-plastic film or an aluminum shell. The anode active material of the anode is lithium iron phosphate material, lithium manganate material, lithium cobaltate material or nickel cobalt manganese lithium ternary material. The current collector of the sheet anode copper foil. The current cathode of the sheet is aluminum foil USE - Used as lithium-ion battery containing silicon cathode. ADVANTAGE - The lithium-ion battery: has small volume effect, excellent multiplying power performance and cycle performance.
