MANUFACTURING METHOD FOR WET GRANULAR BODY OF ELECTRODE ACTIVE MATERIAL MIXTURE, MANUFACTURING METHOD FOR ELECTRODE PLATE, WET GRANULAR BODY OF ELECTRODE ACTIVE MATERIAL MIXTURE, AND MANUFACTURING APPARATUS FOR WET GRANULAR BODY OF ELECTRODE ACTIVE MATERIAL MIXTURE

There are provided a method for manufacturing a wet granular body of an electrode active material mixture from which granular bodies with almost uniform grain size can be obtained, the wet granular body itself, a method for manufacturing an electrode plate using the same, and a manufacturing apparatus for the same. There are provided mixing of obtaining a wet powder body in a pendular state in which solid-matter powder includes at least electrode active material powder and conductive material powder, liquid components exist in facing portions of solid powder but the liquid components are not linked one another in the facing portions, and spaces among the solid powder are entirely linked, and granulating of obtaining an assembly of the wet granular body of the electrode active material mixture by forming the wet powder obtained in the mixing process into grains.
