· JVASP-136362· Li4PCl

Li4PCl is a lithium-based phosphorus-chlorine ceramic compound belonging to the family of lithium phosphate ceramics, which are primarily of research and developmental interest. This material is being investigated for solid-state electrolyte applications in next-generation lithium-ion batteries, where its ionic conductivity and chemical stability are potentially valuable for improving energy density and thermal safety compared to conventional liquid electrolytes. Engineers and materials scientists are exploring this compound as part of broader efforts to enable all-solid-state battery technology for electric vehicles and high-energy-density portable electronics, though the material remains largely in the experimental phase outside specialized research laboratories.
