Abstract
Official abstract text for this publication.
Provided is a method of producing a sulfide solid electrolyte which brings low costs, and large sulfur reducing effect, the method comprising heat-treating material for a sulfide solid electrolyte at a temperature no less than a melting point of elemental sulfur while vibrating the material.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of producing a sulfide solid electrolyte, the method comprising: heat-treating a sulfide solid electrolyte at a temperature no less than a melting point of elemental sulfur and equal to or over a crystallization temperature of the sulfide solid electrolyte while vibrating the sulfide solid electrolyte to obtain a sulfide solid electrolyte of glass ceramic, wherein the heat-treating while vibrating is carried out under a reduced pressure of an inert gas or in a presence of a gas flow, wherein a vibration frequency of the vibrating is 10 to 1000 Hz and an amplitude of the vibrating is 1 to 10 mm, and wherein a time of the heat-treating is no less than 10 minutes and no more than 4.5 hours. 2. The method of producing a sulfide solid electrolyte according to claim 1 , wherein the sulfide solid electrolyte is synthesized from raw materials for an electrolyte, the raw materials containing at least Li 2 S, and one or more sulfide(s) selected from P 2 S 3 , P 2 S 5 , SiS 2 , GeS 2 , B 2 S 3 and Al 2 S 3 . 3. The method of producing a sulfide solid electrolyte according to claim 2 , wherein the raw materials for an electrolyte contain at least Li 2 S and P 2 S 5 . 4. The method of producing a sulfide solid electrolyte according to claim 1 , the method further comprising: prior to the heat-treating while vibrating, pulverizing the sulfide solid electrolyte. 5. The method of producing a sulfide solid electrolyte according to claim 1 , wherein the heat-treating while vibrating is sufficient to fluidize the sulfide solid electrolyte.
