LITHIUM NITRIDE COMPOSITION FOR SULFIDE-BASED INORGANIC SOLID ELECTROLYTE MATERIAL

Provided is a lithium nitride composition for a sulfide-based inorganic solid electrolyte material including α-lithium nitride, wherein in a spectrum obtained by X-ray diffraction in which a CuKα ray is used as a radiation source, when a diffraction intensity of a diffraction peak present at a position of a diffraction angle 2θ=23.0±0.3° is represented by I and a diffraction intensity of a diffraction peak present at a position of a diffraction angle 2θ=32.0±0.3° is represented by I, a value of I/I is 4.50 or lower.
