▎ 摘　　要

NOVELTY - Lithium battery anode current collector comprises a current collector main body comprising a coating layer coated porous structure. The porous structure is formed by compounding and coating lithium carbonate film with metal lithium particles of different diameters. The coating layer is formed by coating with a slurry, and the slurry composition includes a coating material mixed with a binder, a conductive agent, and a solvent water. The coating material mixed binder of the coating layer adopts polyacrylate, and the conductive agent comprises at least one of conductive graphite, conductive carbon black, single-walled, multi-walled carbon nanotubes and/or graphene. USE - The lithium battery anode current collector is useful in battery (claimed). ADVANTAGE - The collector: has a long cycle life, high mode efficacy and strong activity; is safe; provides active lithium in the circulation process that is continuously exposed and electrolyte contact finally realizing the purpose of non-attenuation of the electric core circulation; and exposes the large particle inert lithium metal part active lithium contact anode active material by controlling the size of the variable force so as to contact more movable lithium ion for lithium ion. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Preparing lithium battery anode current collector; and (2) preparing battery cell.
