▎ 摘  要

NOVELTY - The electrode (100) has two electrode mixture layers (30,40) formed on a surface of an electrode current collector (10). An electrode active material and a conductive material are provided in the electrode mixture layer. An electrode assembly is provided with an electrode tab (20) that is connected to an electrode assembly. An electrical conductivity of one of the electrode layers is 3 to 5 times greater than that of the other electrode layer. The conductive materials are selected from a group consisting of carbon nanotube and graphene, and carbon black and graphite. USE - Electrode for lithium secondary battery used in hybrid electric vehicle (HEV) or an electric vehicle. ADVANTAGE - The electrode induces flow of electrons to an edge of a cell so as to induce a uniform flow of current, so that local deterioration can be prevented and lifespan of the cell can be greatly improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing the Electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrode.
