BINDER FOR ELECTRODE OF NON-AQUEOUS ELECTROLYTE SECONDARY CELL, ELECTRODE FOR NON-AQUEOUS SECONDARY CELL CONTAINING SAID BINDER, AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL PROVIDED WITH SAID ELECTRODE

摘要

Provided is a binder for an electrode of a non-aqueous electrolyte secondary cell enabling effective suppression of separation of an electrode mixture from a collector and desorption of an active material, and having excellent binding consistency even under repeated charging and discharging. The binder for an electrode of a non-aqueous electrolyte secondary cell comprises an alkyl-modified carboxyl-group-containing copolymer obtained by copolymerizing (meth)acrylic acid and a (meth)acrylic acid alkyl ester in which the alkyl group has 18-24 carbons.
