Abstract
The present invention relates to a method for manufacturing a binder composition for a lithium-ion secondary battery electrode. The method comprises a step of dissolving a polymer having a melting point in a range of 50° C. to 150° C. in a monomer and obtaining a monomer solution in which the polymer is dissolved in the monomer; and a step of obtaining a composite polymer particle by subjecting the monomer solution to suspension polymerization or emulsion polymerization in an aqueous medium. The binder composition contains the composite polymer particle.
