Abstract
The present invention relates to a binder composition for a secondary battery, an electrode slurry composition including the same, and an electrode and a secondary battery manufactured by using the same, the binder composition including: a latex particle (A) which is a polymer of a monomer mixture including (a1) a conjugated diene monomer, (a2) an ethylenically unsaturated carboxylic acid monomer, and (a3) an aromatic vinyl monomer; and an emulsifier (B), wherein the (a2) ethylenically unsaturated carboxylic acid monomer is included in an amount of 3 parts by weight or more based on 100 parts by weight of the monomer mixture and the emulsifier (B) is included in an amount of less than 3000 ppm based on 100 parts by weight of the latex particles.
