A solid electrolyte glass at least including: at least one alkali metal element; a phosphorus (P) element; a sulfur (S) element; and one or more halogen elements selected from I, Cl, Br and F; wherein the solid electrolyte glass has two exothermic peaks that are separated from each other in a temperature range of 150&#xb0; C. to 350&#xb0; C. as determined by differential scanning calorimetry (in a dry nitrogen atmosphere at a temperature-elevating speed of 10&#xb0; C./min from 20 to 600&#xb0; C.).

Solid electrolyte

A method for producing sulfide-based glass ceramics including crystallizing a glass solid electrolyte, wherein the glass solid electrolyte includes: sulfide-based glass comprising at least a sulfur element and a lithium element; and a nitrile compound incorporated into the sulfide-based glass.

Sulfide glass, and method for producing sulfide glass ceramic

A solid electrolyte including an alkali metal element, phosphorous, sulfur and halogen as constituent components.

A method for producing a solid electrolyte including step of bringing the following into contact with each other in a solvent having a solubility parameter of 9.0 or more: an alkali metal sulfide; one or two or more sulfur compounds selected from phosphorus sulfide, germanium sulfide, silicon sulfide and boron sulfide; and a halogen compound.

Method for producing solid electrolyte

Glass particles including Li, P and S, wherein when a Raman spectrum of the glass particles is measured five times or more and a peak at 330 to 450 cmin the Raman spectrum is separated into peaks of components by waveform separation, the standard deviation of the area ratio of each of the peaks of the components is 3.0 or less, the area of the peak of PScomponent obtained by the waveform separation is 10 to 95% of the total area, and the area of PScomponent obtained by the waveform separation is 5 to 45% of the total area, and the area of the peak of PScomponent is larger than the area of the peak of PScomponent.
