Abstract
A positive electrode mixture comprising at least one of a titanium sulfide TiSx (2<x<10) and a discharge product of the titanium sulfide and a sulfide solid electrolyte having a diffraction peak for which 2θ is 20.1±0.4° in X-ray diffraction using a CuKα ray.
Claims12
A positive electrode mixture comprising:
- at least one of a titanium sulfide TiSx (2<x<10) and a discharge product of the titanium sulfide;
- and
- a sulfide solid electrolyte having a diffraction peak for which 2θ is 20.1±0.4° in X-ray diffraction using a CuKα ray.
A production method for a positive electrode mixture, the method comprising a step of mixing a titanium sulfide TiSx (2<x<10) that satisfies the following (A) and a sulfide solid electrolyte that satisfies the following (B):
- (A) in X-ray diffraction using a CuKα ray, the titanium sulfide has a diffraction peak for which 2θ is 34±1° and a diffraction peak for which 2θ is one or more selected from 15.5±1°, 44±1°, and 54±1°, and
- (B) in X-ray diffraction using a CuKα ray, the sulfide solid electrolyte has a diffraction peak for which 2θ is 20.1±0.4°.
