· JVASP-147152· Li4Fe3WO8

Li₄Fe₃WO₈ is a lithium iron tungstate ceramic compound belonging to the mixed-metal oxide family, synthesized primarily for energy storage and electrochemical applications. This material is investigated in research contexts for lithium-ion battery cathode and solid electrolyte applications, where its mixed valence structure and ionic conductivity properties are of interest for next-generation energy storage systems. The incorporation of tungsten into a lithium-iron-oxide framework offers potential advantages in electrochemical stability and cycling performance compared to simpler binary oxide systems.

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.
