Document Type and Number:

WIPO Patent Application WO/2012/173072

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing an electrode-forming composition, which is used for the purpose of producing a secondary battery that has excellent charge and discharge cycle characteristics, and which exhibits excellent dispersibility of an active material and a conductive assistant. The problem is solved by a composition for forming a secondary battery electrode, which contains (A) an electrode active material and/or (B) a carbon material that serves as a conductive assistant, (C) an amphoteric resin-type dispersant that is obtained by neutralizing at least some carboxyl groups in a copolymer containing aromatic rings, carboxyl groups and amino groups with a basic compound, and (D) an aqueous liquid medium.
