· Li2 Fe1 Br4

Li₂Fe₁Br₄ is a halide-based semiconductor compound combining lithium, iron, and bromine in an ionic crystal structure. This material belongs to the emerging class of halide perovskites and related semiconducting halides, primarily of research interest for next-generation optoelectronic and energy storage applications. While not yet widely deployed in commercial products, compounds in this family are being investigated for potential use in solid-state batteries, photovoltaic devices, and scintillator applications due to the semiconductor bandgap engineering possibilities offered by halide compositions.

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.
