A cubic space having a crystal structure belonging to the group F-43m, the composition formula: Li 7 - x PS 6 -x Ha x relates to a compound represented by (Ha is Cl or Br),, as a low charge and discharge by the electronic conductivity Thereby providing a solid electrolyte capable of improving efficiency and cycle characteristics. Cubic and has a crystal structure belonging to the space group F-43m, In addition, the composition formula: Li 7 - PS x 6 x -x Ha (Ha is Cl or Br) containing a compound represented by, and the x in the composition formula 0.2 And a lightness L * value of the L * a * b * colorimetric system is not less than 60.0. The present invention also provides a sulfide-based solid electrolyte for a lithium ion battery. |
