· JVASP-34903· Li4P2O7

Li4P2O7 is a lithium phosphate ceramic compound belonging to the family of lithium orthophosphates, engineered for electrochemical and thermal applications. This material is primarily investigated in research contexts as a solid electrolyte and ionic conductor for next-generation lithium-ion battery systems, where its lithium-ion transport properties make it attractive for all-solid-state battery architectures that offer higher energy density and improved thermal stability compared to conventional liquid electrolytes. Engineers consider this compound when designing advanced energy storage systems where ceramic electrolytes can enable safer, longer-cycle-life batteries for electric vehicles, grid storage, and high-performance portable devices.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
