Title:
GRAPHENE DISPERSION, GRAPHENE RESIN POWDER, AND BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/045286
Kind Code:
A1
Abstract:
Provided is a graphene dispersion in which graphene and a polymer are dispersed or dissolved in a solvent, wherein the weight average molecular weight of the polymer is 10,000 to 800,000, the graphene dispersion has a viscosity of 500 to 10,000 (mPa·s) measured at a measurement temperature of 25°C and a rotation speed of 50 rpm by using a B-type viscometer, and a value obtained by dividing the viscosity of the graphene dispersion measured at a measurement temperature of 25°C and a rotation speed of 5 rpm by using a B-type viscometer by the viscosity of the graphene dispersion measured at a measurement temperature of 25°C and a rotation speed of 50 rpm by using the B-type viscometer is 1.2 to 5.0.
