▎ 摘　　要

NOVELTY - Lithium battery current collector comprises high molecular film, first bonding force reinforcing layer covered on upper surface of high molecular film, second bonding force reinforcing layer covered on lower surface of high molecular film, third material layer covered on surface of first bonding force enhancement layer, fourth material layer covered on surface of second bonding force enhancement layer, fifth material layer covered on the surface of the third material layer, sixth material layer covered on the surface of the fourth material layer, seventh material layer covered on the surface of the fifth material layer and an eighth material layer covered on the surface of the sixth material layer. The third material layer and fourth material layer are the material layer with conductive function. The fifth material layer and sixth material layer comprise polymer base material(s). The seventh material layer and eighth material layer are the material layer with conductive function. USE - The lithium battery current collector is used for lithium battery (claimed). ADVANTAGE - The collector can improve energy density of a lithium battery and safety performance of the lithium battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the lithium battery current collector. DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of lithium battery current collector.
