FAST-CHARGING ANODE SHEET, LITHIUM-ION BATTERY, AND ELECTRIC DEVICE

Provided are a fast-charging anode sheet, a lithium-ion battery, and an electric device. The anode active material in the anode material layer of the fast-charging anode sheet includes a silicon-based material and a carbon-based material; based on the mass of the anode active material as 100%, a mass fraction of the silicon-based material in the anode active material is 70 wt %-99.5 wt %, and a mass fraction of the carbon-based material is 0.5 wt %-30 wt %. The anode active material in the anode material layer of the fast-charging anode sheet includes a silicon-based material and a carbon-based material, and the silicon-based material is the main component of the anode active material, which ensures a high gravimetric capacity and fast-charging performance of the anode material layer, and brings about a low areal density of the anode material layer, thus the lithium-ion battery prepared by the coordination of the fast-charging anode sheet and the cathode sheet having a high areal density, has high energy density and can achieve high-rate charging as well; the fast-charging anode sheet has the advantages of low production cost and simple production process.
