Document Type and Number:
Japanese Patent JP2019061755
Kind Code:
A
Abstract:
To provide a mixture paste for a lithium ion battery positive electrode, which is suppressed an increase in viscosity and has a viscosity facilitating coating.SOLUTION: A method of producing a conductive paste for a lithium ion battery positive electrode includes the steps of: dispersing a mixed liquid containing a dispersion resin (A-1), polyvinylidene fluoride (B), conductive carbon (C) and a solvent (D) to obtain a dispersion liquid; and then adding a dispersion resin (A-2) to the dispersion liquid. In the method, a dispersion resin (A-1) and/or a dispersion resin (A-2) includes a resin having a polycyclic aromatic hydrocarbon group and/or an amide group.SELECTED DRAWING: None
