Abstract
The present disclosure provides a method of producing a sulfide solid electrolyte material which includes a preparing process of preparing composite particles including a solid solution including a Li2S component and a LiBr component; an addition process of adding the composite particles and a phosphorus source to a reaction chamber; and a milling process in which a mechanical milling treatment is performed on the composite particles and the phosphorus source in the reaction chamber while thermal energy is applied.
Claims17
A method of producing a sulfide solid electrolyte material, comprising:
- a preparing process of preparing composite particles including a solid solution including a LiI component, a Li2S component and a LiBr component, wherein
- the LiI component, the Li2S component and the LiBr component are solid-solutionized such that the solid solution comprises a LiBr rich phase in which the LiBr component is a main component of the LiBr rich phase, and in an XRD measurement using CuKα rays, a peak position of the (111) plane of the LiBr rich phase is shifted 0.1° or more to a lower angle side of a peak position of the (111) plane of LiBr;
- an addition process of adding the composite particles and a phosphorus source to a reaction chamber;
- and
- a milling process in which a mechanical milling treatment is performed on the composite particles and the phosphorus source in the reaction chamber while thermal energy is applied.
