Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a binder composition for a lithium-ion secondary battery electrode comprising: 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, wherein the binder composition contains the composite polymer particle the polymer is a hydrogenated copolymer of aromatic vinyl with conjugated diene, and the monomer solution is obtained by dissolving the polymer in an amount of 5 to 100 parts by weight with respect to 100 parts by weight of the monomer. 2. The method for manufacturing a binder composition for a lithium-ion secondary battery electrode according to claim 1 , wherein the polymer is manufactured by a solution polymerization method. 3. The method for manufacturing a binder composition for a lithium-ion secondary battery electrode according to claim 2 , wherein the polymer manufactured by the solution polymerization method is a block copolymer. 4. The method for manufacturing a binder composition for a lithium-ion secondary battery electrode according to claim 1 , wherein the composite polymer particle has a core-shell structure in which a shell portion containing a polymer having a binding property is further formed on a surface of the composite polymer particle.
