Abstract
Provided is a solid electrolyte with which charge/discharge efficiency and cycle characteristics can be increased by reducing the electron conductivity of a compound which has a cubic crystal structure belonging to a space group F-43m, and is represented by Compositional Formula: LiPSHa(Ha is Cl or Br). Proposed is a sulfide-based solid electrolyte for a lithium ion battery, which includes a compound having a cubic crystal structure belonging to a space group F-43m, and being represented by Compositional Formula: LiPSHa(Ha is Cl or Br), in which x in the above Compositional Formula is 0.2 to 1.8, and the value of the lightness L* thereof in the L*a*b* color system is 60.0 or more.
