Title: SULFIDE SOLID ELECTROLYTE PARTICLE
Abstract:
Provided is a sulfide solid electrolyte particle containing lithium, phosphorus, and sulfur, wherein the volume-based average particle diameter as measured by a laser diffraction-type particle size distribution measurement is 0.1-10 μm, and in a diffraction pattern obtained from a powder X-ray diffraction measurement using CuKα radiation, a diffraction peak is present in the 2θ range of 29.0 to 31.0 degrees, and the intensity ratio of the diffraction intensity Ib at a high angle-side lower part of the diffraction peak to the peak intensity Ip of the diffraction peak, i.e. Ib/Ip, is less than 0.09.
