· JVASP-45400· CaPS3

CaPS3 (calcium polysulfide) is a ceramic compound in the sulfide family, representing an emerging material of interest in solid-state chemistry and materials research. While not yet widely commercialized, calcium polysulfides are being investigated for potential applications in solid electrolytes and energy storage systems, particularly for next-generation battery technologies where sulfide-based ceramics offer ionic conductivity and chemical stability advantages over conventional oxide ceramics.
