▎ 摘　　要

NOVELTY - Lithium battery anode pole piece comprises am anode current collector and an anode coating layer. The anode current collector has two opposite surfaces, and at least one surface of the anode current collector is coated with the anode coating layer. The anode coating layer includes a first coating layer, a second coating layer and a third coating layer distributed outward from one side of the anode current collector; The total thickness of the anode coating layer is 200±10 μm, the first coating layer is 20±5 μm, the thickness of the first coating layer: the thickness of the second coating layer: the thickness of the third coating layer=1:4:5. The active material of the first coating layer is graphene USE - Positive electrode piece for lithium battery. ADVANTAGE - The lithium-rich lithium manganate anode the pole piece is low in price, multuiple materials are mixed, can reduce the cost of the material and the battery and increase the benefit. The technical process of the invention is simple, the battery capacity is improved without changing the size of the battery. The safety performance of battery is increased. The lithium battery anode piece solves the problem of low first effect, fast circulation attenuation and low specific capacity in the existing technology. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparation method of the lithium battery anode pole piece. Lithium electronic battery. DESCRIPTION OF DRAWING(S) - The drawing shows a spray structure schematic diagram of lithium battery anode pole piece (Drawing includes non-English language text).
