Phosphorus Sulfide, Powder, 99.9%, -625 mesh approx

Phosphorus pentasulfide is a critical precursor in the synthesis of sulfide-based solid-state electrolytes, such as Li2S-P2S5, which provide high ionic conductivity for next-generation solid-state batteries.

Used as a reagent to introduce sulfur into electrode architectures or to synthesize thio-phosphates that serve as protective coatings or active components in high-performance lithium battery systems.
