Abstract
This invention is a method for producing an electrode for a non-aqueous electrolytic cell, in which a collector is coated with an electrode active material layer comprising an active material, flake graphite and a binder, which is characterized by that the graphite is subjected to a pulverization process twice or more, followed by mixing and pulverization using the active material, and provides an electrode for a secondary cell which is good in charge and discharge characteristics such as discharge capacity and charge and discharge cycle life, and improved in physical characteristics.
