Abstract

The present invention provides a conductive paste for positive electrodes of lithium-ion batteries and mixture paste for positive electrodes of lithium-ion batteries that have an easy-to-apply viscosity, even when a relatively small amount of a dispersant is incorporated. More specifically, the present invention provides a conductive paste for positive electrodes of lithium-ion batteries containing a dispersion resin (A), conductive carbon (B), and a solvent (C), the dispersion resin (A) being a copolymer of a monomer mixture comprising a polycyclic aromatic hydrocarbon-containing monomer (A-1) in an amount of 1 to 70 mass %, based on the total solids content.
