Abstract
(EN)
This production method is for producing a sulfide inorganic solid electrolyte material including Li, P and S as constituent elements. The method includes a preparation step for preparing a material inorganic composition (A) containing at least lithium sulfide, phosphorus sulfide and a crystal nucleator; and a vitrification step for vitrifying the material inorganic composition (A) by subjecting the material inorganic composition (A) to mechanical processing.
