Abstract

Official abstract text for this publication.

An electrode for secondary batteries, the electrode includes a current collector foil, a first mixture layer, and a second mixture layer. The first mixture layer is a layer of granulated particles accumulated on the current collector foil. The granulated particles contain at least an active material and a binder. The second mixture layer is a layer of a mixture paste applied to a surface of the first mixture layer and then dried. The mixture paste is obtained by kneading at least an active material, a binder, and a solvent.
