Document Type and Number:
WIPO Patent Application WO/2020/045246
Kind Code:
A1
Abstract:
Provided is a composition for a nonaqueous secondary battery adhesive layer that contains organic particles, a thixotropic agent, and water, for which the organic particles have a core-shell structure comprising a core part and a shell part that at least partially covers the outer surface of the core part, and for which the viscosity η0 at a shear rate of 100 sec–1 is less than 10 mPa•s, the viscosity η1 at a shear rate of 10,000 sec–1 is 0.5 to 2.4 mPa•s (inclusive), and the ratio (η0/ η1) of viscosity η0 to viscosity η1 is 1.2 to 10 (inclusive).
