Abstract
According to this method for producing an electrode, a fibrous binder is produced by fibrillating a particulate binder, which has a volume-based median diameter of from 5 to 100 μm, by means of the application of a shear force, and an electrode mixture is produced by mixing the fibrous binder with an active material, said electrode mixture having a solid content concentration of substantially 100%. It is preferable that the fibrillation is carried out so that the breaking peripheral velocity ratio of the electrode mixture is 8 or more. In addition, an electrode mixture sheet is produced by shaping the electrode mixture into a sheet form by rolling, and the electrode mixture sheet is subsequently bonded to a core material.
