· JVASP-43556· Li5FeF8

Li5FeF8 is a lithium iron fluoride compound being investigated as a solid-state electrolyte and cathode material for next-generation lithium-ion batteries. This ionic compound combines lithium's high electrochemical potential with iron and fluoride constituents to achieve enhanced ionic conductivity and electrochemical stability, positioning it as a research material for high-energy-density battery systems. The material remains largely in the experimental phase, with potential applications in automotive electric powertrains and grid-scale energy storage where conventional liquid electrolytes present thermal or safety limitations.

Export Control

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.
