Abstract

Official abstract text for this publication.

A method for efficiently producing fine particles in a complex state from a plurality of raw material components is provided. The method includes spraying a good solvent solution made from a good solvent and the plurality of raw material components dissolved in the good solvent into a poor solvent having a temperature of at least 165° C. higher than the boiling point of the good solvent and evaporating off the good solvent and precipitating a plurality of fine particles.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method for producing particles comprising: spraying a good solvent solution comprising a good solvent and a plurality of raw material components dissolved in the good solvent into a poor solvent having a temperature of at least 165° C. higher than the boiling point of the good solvent, to evaporate off the good solvent and precipitate the plurality of particles. 2 . The method for producing particles according to claim 1 , wherein the good solvent solution is in a slurry further comprising at least one type of raw material component in powdered form dispersed in the good solvent. 3 . The method for producing particles according to claim 1 , wherein a total concentration of the plurality of raw material components dissolved in the good solvent is 10 g/l or greater. 4 . The method for producing particles according to claim 1 , wherein the plurality of raw material components are lithium sulfide, lithium iodide and lithium bromide, and the particles are raw material particles of a solid electrolyte material. 5 . Solid solution particles comprising: sulfur, lithium, iodine and bromine as solid solution components, wherein positions of peaks from x-ray diffraction using CuKα rays attributable to the (111) faces of lithium sulfide, lithium iodide and lithium bromide are in a range of diffraction angle 2θ=25.9° or greater and less than 28.0°, and wherein a mean primary particle size of the particles is no greater than 5 μm.
