A method for producing a coated active material includes dropletizing a slurry to obtain slurry droplets wherein the slurry contains an active material and a coating liquid, gas-flow drying the slurry droplets in a heating gas to obtain a precursor, and firing the precursor.

Coated active material production method and coated active material

Provided is a method for manufacturing an active material mixture, the method including: supplying and dispersing a solid electrolyte in a dispersion medium while circulating the dispersion medium (a first dispersion step); and thereafter supplying and dispersing an active material and a conductive material in the dispersion medium (a second dispersion step), wherein an average rotation speed of the rotor in the second dispersion step is lower than an average rotation speed of the rotor in the first dispersion step. Aggregation of the solid electrolyte can be suppressed by separately performing the first dispersion step and the second dispersion step, and the increase in temperature of the active material mixture can be reduced by lowering the rotation speed of the rotor in the second dispersion step.

Method and apparatus for manufacturing active material mixture

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.
