Abstract

The present disclosure provides an electrode for a secondary battery and a lithium secondary battery including the same. The electrode for a secondary battery according to the present disclosure includes an electrode current collector, and an electrode active material layer disposed on one surface of the electrode current collector, and including an electrode active material and a graphene conductive material. The number of layers of the graphene conductive material, as defined by Equation 1, is 2 to 15. Numberoflayers=Lc/D+1 (in Equation 1, Lc represents a grain size (Å) and D represents a d-spacing (Å), calculated from X-ray diffraction (XRD) analysis results of the graphene conductive material)
