Beschreibung
Zusammenfassung:	A sulfide solid electrolyte of the present invention contains from 100 ppm or more to 1000 ppm or less of aluminum on a mass basis, it has lithium ion conductivity, and contains lithium element, phosphorus element, and sulfur element. The aluminum is preferably derived from aluminum oxide. The sulfide solid electrolyte is also preferably one having an argyrodite-type crystal structure. The sulfide solid electrolyte is preferably provided with a lithium ion conductivity of 4.0 mS/cm or more. The present invention also provides an electrode composition containing a sulfide solid electrolyte and an active material.
