Title:
BINDER COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODE, CONDUCTIVE MATERIAL PASTE COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODE, SLURRY COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODE, NONAQUEOUS SECONDARY BATTERY ELECTRODE, AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/181744
Kind Code:
A1
Abstract:
Provided are: a slurry composition for a nonaqueous secondary battery electrode, the slurry composition having excellent viscosity stability; and a binder composition for a nonaqueous secondary battery electrode, the binder composition being capable of forming a nonaqueous secondary battery having excellent cycle characteristics. This binder composition for a nonaqueous secondary battery electrode includes a polymer comprising a monomer unit having a functional group capable of binding to a cationic group and a (meth)acrylic ester monomer unit, and an organic compound having two or more cationic groups, wherein the rate of change in viscosity is 400% or less when the binder composition is left standing for 30 days at 60°C.
