An object of the present invention is to further lower the viscosity of a sulfur compound solid electrolyte dispersion paste while suppressing sedimentation of a sulfur compound solid electrolyte. Provided is a sulfur compound solid electrolyte dispersion paste for secondary batteries, containing a dispersion resin (A), a sulfur compound solid electrolyte (B) and a solvent (C), wherein the dispersion resin (A) contains at least one type of acrylic resin (a) having a weight-average molecular weight of 3000 or higher.

The present invention provides a conductive paste for positive electrodes of lithium-ion batteries and a mixture paste for positive electrodes of lithium-ion batteries that are inhibited from increasing in viscosity and gelling, and that have an easy-to-apply viscosity. The conductive paste of the present invention contains a dispersion resin (A), polyvinylidene fluoride (B), conductive carbon (C), a solvent (D), and a dehydrating agent (E).

Conductive paste and mixture paste for lithium ion battery positive electrode

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.
