Abstract
In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, the disclosure, in one aspect, relates to oxyhalide electrolytes and synthesis of oxyhalide electrolytes. The electrolytes have the general formula AzNv−yLyOX5−2y, exhibit superionic conductivity, and can be produced via a relatively fast synthesis route. The electrolytes can be a component of different types of batteries.
