Title:
非水電解質二次電池電極合剤層用組成物及びその製造方法、並びに、その用途
Document Type and Number:
Japanese Patent JP6665857
Kind Code:
B2
Abstract:
Provided is a composition for an electrode mixture layer of a nonaqueous electrolyte secondary battery, said composition containing an active material, water, and a binder. The binder includes: a crosslinked polymer of a monomer component containing an ethylenically unsaturated carboxylic acid monomer; and a salt of the crosslinked polymer. The viscosity of a 0.5 wt% aqueous dispersion of the crosslinked polymer at a neutralization degree of 90 mol% is 5,000-40,000 mPa∙s. The content of the crosslinked polymer and the salt thereof is 0.5-5.0 wt% relative to the active material.
