▎ 摘  要

NOVELTY - The electrode comprises an electrode active material layer, which includes an electrode active material and a conductive material. The conductive material includes a first conductive material and a second conductive material. The secondary particles are connected to a portion of the graphene sheet. The secondary particles include multiple graphene sheets, which are arranged in different directions. The second conductive material is 2 to 5000 single-walled carbon nanotube units. A carbon nanotube structure is bonded to each other, where the carbon nanotube structure is contained in an amount of 0.01 percent to 0.5 percent by weight in the electrode active material layer. USE - Electrode for use in a secondary battery (claimed) of electric vehicle, hybrid electric vehicle, plug-in hybrid electric vehicle, and power storage system. ADVANTAGE - Ensures to reduce the total conductive material content for an appropriate level of conductivity, and the input or output characteristics and life characteristics of the battery can be greatly improved, because the electrical conductivity and adhesion of the electrode can be improved at the same time. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of a process of forming a graphene sheet contained in the secondary particles. (Drawing includes non-English language text).
