NOVELTY - The method comprises binding active material particles and a first conductive material formed of a carbon material with a first binder to form carbon bond active material particles in which the first conductive material is evenly bound over the surface of the active material particles, and forming (S2) an electrode mix paste by mixing the carbon bond active material particles, a second conductive material, a second binder and a first solvent with a mixer having a cylindrical mixing vessel and a rotary blade that is provided in the mixing vessel.    USE - The method is useful for producing an electrode plate for a secondary battery (claimed) such as a lithium-ion secondary battery, which is useful as an electric source of a portable device, a mobile device, an electric vehicle or a hybrid vehicle.    ADVANTAGE - The method is capable of efficiently producing electrode plates with high-yield using the electrode mix paste thus providing improved high current discharge characteristics and reduced internal resistance to the secondary battery.    DETAILED DESCRIPTION - The method comprises binding active material particles and a first conductive material formed of a carbon material with a first binder to form carbon bond active material particles in which the first conductive material is evenly bound over the surface of the active material particles, forming (S2) an electrode mix paste by mixing the carbon bond active material particles, a second conductive material, a second binder and a first solvent with a mixer having a cylindrical mixing vessel and a rotary blade that is provided in the mixing vessel, rotates and moves near an inner circumferential surface of the mixing vessel and includes a cylinder portion in which holes are formed, and applying (S3) the electrode mix paste on a collector member. The carbon bond active material particles, the second conductive material, the second binder and the first solvent put in the mixing vessel are mixed by the rotary blade to the inner circumferential surface of the mixing vessel extended into a cylindrical thin film. The carbon bond active material particles, the second conductive material, the second binder and the first solvent are mixed for five to ten minutes. The carbon bond active material particles are formed by a spray dry method. The active material particles and the first conductive material are bound by the first binder and by spraying liquid formed by mixing the first binder and a second solvent into a basin while the active material particles and the first conductive material are fluidized in the basin, and then drying a mixture of the active material particles, the first conductive material and the liquid. INDEPENDENT CLAIMS are included for:    (1) an electrode plate; and    (2) a secondary battery.
