· JVASP-18455· NaSnS2

Sodium tin sulfide (NaSnS₂) is an inorganic ceramic compound belonging to the thiostannate family, characterized by a layered crystal structure with sodium and tin cations coordinated by sulfide anions. This material is primarily investigated in research contexts for energy storage and optoelectronic applications, where its ionic conductivity and semiconducting properties make it a candidate for solid-state batteries, thermoelectric devices, and photovoltaic absorber layers. While not yet widely commercialized, NaSnS₂ represents a promising direction in sustainable materials development due to its earth-abundant constituent elements and potential for tunable electronic properties through doping or structural modification.
