· JVASP-21935· Li3PO4

Lithium phosphate (Li3PO4) is an inorganic ceramic compound belonging to the phosphate family, characterized by its ionic crystal structure and lithium-rich composition. It is primarily investigated in solid-state battery research as a potential solid electrolyte material, where its ionic conductivity and electrochemical stability are of interest for next-generation energy storage systems. Engineers consider Li3PO4 in advanced battery applications because it offers the potential for improved safety, higher energy density, and wider operating temperature ranges compared to conventional liquid electrolytes, though it remains largely in development and commercialization phases.
