▎ 摘　　要

NOVELTY - A sheet comprises an anode material layer. The anode material layer includes an anode active material and a conductive agent. The anode active material is lithium iron phosphate materials, and the conductive agent includes carbon black. The anode material layer satisfies the following conditions: 3.2%≤100*x*a/(τ/ε)≤30.0%, where X is the weight percentage of carbon black in conductive agent, a is the weight percentage of the conductive agent based on the anode active material as 100%, τ is the electrode tortuosity of the anode material layer, and ε is the porosity of the anode material layer. USE - The anode sheet is useful for lithium-ion battery. ADVANTAGE - The anode sheet optimizes liquid phase diffusion resistance and electron conduction performance of the anode material layer, and improves the dynamic performance of the anode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows an equivalent circuit diagram of an anode sheet.
