Abstract
An aqueous binder composition for a secondary battery electrode containing a silane coupling agent without ethylenically unsaturated bonds, a resin which is a polymer of at least one kind of ethylenically unsaturated monomers, a resin which is a polymer of at least one kind of ethylenically unsaturated monomer, and at least one kind of solvent selected from water and a hydrophilic solvent. The amount of silane coupling agent is from 0.5 to 9 parts by mass based on 100 parts by mass of ethylenically unsaturated monomer. The pH of the composition is 2.5 to 8.0. Also disclosed is a binder obtained by curing the aqueous binder composition, a slurry containing the aqueous binder composition and an active material, a secondary battery electrode obtained by curing the slurry, and a secondary battery including the secondary battery electrode.
