▎ 摘  要

NOVELTY - Composite conductive film comprises a base film layer and a conductive layer. The base layer is made of high-molecular polymer, and the conductivity layer is doped with conductive material and modifier. The conductive layers are compounded on both sides of the base film layers in a molten state. USE - The composite conductive film is useful as current collector for lithium battery e.g. lithium-ion battery (claimed). ADVANTAGE - The composite conductive film has good combination fastness, avoids separation and shedding phenomenon caused by insufficient fastness between the base film layer and the conductive layer, has good conductivity, reduces mass of the current collector, improves energy density. The is small, low device investment, high production efficiency, no damage, and strong controllability of the composite film thickness and resin raw material selectivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing composite conductive film. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the method for preparing composite conductive film (Drawing includes non-English language text).
