· JVASP-10979· Ag3PS4

Ag3PS4 is a quaternary silver phosphorus sulfide compound belonging to the family of superionic conductors and mixed-anion solid electrolytes. This is a research-grade material currently under investigation for advanced energy storage and electrochemical device applications, rather than an established commercial material. The compound is of interest primarily in the solid-state ionics community for its potential as a fast ion conductor in all-solid-state batteries and electrochemical sensors, where its unique crystal structure may enable enhanced silver-ion mobility compared to conventional electrolytes.
