· Li4 Fe3 Sb1 O8

Li₄Fe₃Sb₁O₈ is an experimental lithium-iron antimonite ceramic compound being investigated as a potential lithium-ion conductor and cathode material for solid-state and conventional lithium batteries. This mixed-valence oxide belongs to the family of complex lithium metal oxides, where the combination of iron and antimony provides structural flexibility and ionic transport pathways. Research into this composition focuses on energy storage applications where high lithium mobility, electrochemical stability, and thermal robustness are required; it represents the broader effort to develop alternative active materials that can improve battery energy density, cycle life, or safety margins compared to conventional layered oxide cathodes.

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.
