Abstract
A sulfide solid electrolyte according to an aspect of the present invention includes a crystal structure and contains, as constituent elements, one, or two or more divalent elements A, one, or two or more halogen elements X, and a nitrogen element, and the divalent element A and the halogen element X make a combination such that a compound A0.5X composed of the divalent element A and the halogen element X is higher in hydration energy than LiI.
Claims25
A sulfide solid electrolyte comprising a crystal structure, and
- comprising, as constituent elements, one, or two or more divalent elements A, one, or two or more halogen elements X, and a nitrogen element,
- wherein the divalent element A and the halogen element X make a combination such that a compound A0.5X including the divalent element A and the halogen element X is higher in hydration energy than LiI.
A method for producing a sulfide solid electrolyte, comprising treating a composition material including, as constituent elements, one, or two or more divalent elements A, one, or two or more halogen elements X, and a nitrogen element, wherein the divalent element A and the halogen element X make a combination such that a compound A0.5X including the divalent element A and the halogen element X is higher in hydration energy than LiI.
