· Li6 P1 S5 Br1

Li₆PS₅Br is an argyrodite-type solid electrolyte compound combining lithium, phosphorus, sulfur, and bromine in a halide-substituted sulfide framework. This material is an experimental superionic conductor being researched for next-generation solid-state battery applications, where it offers the potential for high ionic conductivity at room temperature while maintaining chemical stability—making it an alternative to oxide-based or pure sulfide electrolytes.
