Abstract:
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.
