▎ 摘  要

NOVELTY - Lithium-supplementing anode pole piece comprises a anode current collector, a anode active material layer and a lithium replenishing reagent layer (2) coated on the anode current collector. The single lithium-supplementing reagent layer and the single anode active material layer are arranged along the length direction of the current collector. The lithium-supplementing agent layer and the anode active material layer are arranged at intervals along the width direction of the current collector on the surface of the current collector. USE - Used as lithium-supplementing anode pole piece. ADVANTAGE - The lithium-supplementing anode pole piece: does not affect the electronic conduction of the material layer anode; does not deteriorate the transmission path of the ion lithium; improves the fast charging, and the concentration difference polarization when discharging; makes the performance of each performance of anode active substance and the lithium-replenishing agent maximize; maximizes the effect of lifting the lithium replacement agent; and improves the energy density and cycle life of the electric core. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a preparation method of the lithium anode pole piece; and (2) lithium ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the lithium-supplementing anode pole piece. 2Lithium reagent layer 3Active substance anode
