An aqueous electrode mixture is provided that provides a non-aqueous electrolyte secondary battery in which the rate of decrease in discharge capacity compared to the case of using an organic solvent-based binder is suppressed. An electrode mixture containing a granular electrode active material, a conductive material, and a binder, wherein the electrode active material adheres to the granular core material and the surface of the core material in the form of particles or layers. The core material is obtained by a method having a step of coprecipitation of two or more transition metal elements, and the binder is selected from the group consisting of a water-soluble polymer and a water-dispersible polymer. An electrode mixture that is at least one or more. An electrode obtained by applying the electrode mixture to a current collector and drying. An electrode mixture paste containing the electrode mixture and water. A non-aqueous electrolyte secondary battery having a positive electrode, a negative electrode, and an electrolyte, wherein the positive electrode is the electrode. [Selection figure] None |
