Patent ID: 10297819

Abstract:
A slurry composition for a lithium ion secondary battery negative electrode including a negative electrode active material, a conductive material, a water-soluble polymer, and a particulate binder, wherein an amount of the conductive material with respect to 100 parts by weight of the negative electrode active material is 0.1 parts by weight to 10 parts by weight, the water-soluble polymer has a 1% aqueous solution viscosity of 10 mPa·s to 3,000 mPa·s, and the particulate binder contains a particulate binder A having a surface acid amount of 0.01 meq/g or more and 0.10 meq/g or less and a particulate binder B having a surface acid amount of 0.15 meq/g or more and 0.5 meq/g or less.
