Abstract
In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, the disclosure, in one aspect, relates to solid chalcohalide electrolytes and the efficient synthesis of solid chalcohalide electrolytes. The electrolytes have the general formula AaMbNcXdYeSf and have relatively high ionic conductivity. The electrolytes can be a component of different types of batteries. The process of synthesizing the electrolytes can be done with cost-effective materials, which is useful for scaling-up production of batteries such as all-solid-state batteries.
