発明の名称 (英語) BINDER, USE THEREOF AND METHOD FOR PRODUCING ELECTRODE
発明の概要(英語) The purpose of the present invention is to provide an aqueous binder which enables use of an active material that is highly reactive with water by suppressing deterioration of the active material, while ensuing high electrode strength with a small amount of use and enabling an electrode to achieve high output characteristics and the like. This binder connects an active material and a conductive assistant, which are materials for electrodes of electrochemical devices, and is characterized by containing protons in the system.
