▎ 摘　　要

NOVELTY - Composite electrode comprises a current collector (1), an active material layer (3) compounded on the surface of the current collector and a structure lithium layer compounded at the same surface of an activated material layer. The structural lithium layer comprises lithium and a structured additive. The structured additive passes through the structured lithium layer and forms a physical contact with the active materials layer. The structured additive is graphite, soft carbon, hard carbon, conductive carbon black, carbon fiber, acetylene black, kojen black, titanium oxide, conductivity polymer particles and/or carbon graphene-tube. USE - The electrode is useful for lithium ion battery in class-3 digital products and power batteries. ADVANTAGE - The utilization rate of the composite electrode lithium metal is improved, and the electric core impedance is reduced. The lithium metal utilization rate is high and the dead lithium covered cathode pole piece the surface is increased impedance, the lithium metal layer is designed with a through structure, compared with the existing method for calendering and supplementing lithium, the utilization ratio of lithium metal from 55% lifting value is 90% from 55% lifting value, the alternating current impedance of the electric cores is reduced by 25% and the retention rate of circulating 1500cls at 40℃ is increased by 5% and 0.5P charging and discharging efficiency by 94.0% lifting values is 94.6%. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a preparation method of composite electrode; and a lithium-ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a structural representation of compound electrode among the composite electrode for lithium ion battery in e.g. power batteries. 1Current collector 2Comparative example 3Active material layers
