Electrode material for electric double layer capacitor, method for producing the same, electrode for electric double layer capacitor and electric double layer capacitor

摘要

An electrode material for an electric double layer capacitor, where a moldability is good, a flexion resistance and a cohesiveness to a current collector after molding into an active material layer are high and an internal resistance can be reduced, an electrode for an electric double layer capacitor obtained using the electrode material, and a capacitor are provided. The electrode material for the electric double layer capacitor is composed of a mixture particle containing a binder and an electrode active material, and in said mixture particle, 50 area % or more of a surface of said mixture particle has been coated with the binder.
