· Li2 Fe1 Ni1 O4

Li₂Fe₁Ni₁O₄ is a mixed-metal lithium oxide compound belonging to the spinel or layered oxide family of semiconductors, synthesized for energy storage and electrochemical applications. This material is primarily of research interest for lithium-ion battery cathodes and solid-state battery systems, where the combination of lithium, iron, and nickel cations offers tunable electrochemical potential and cycling stability compared to single-transition-metal alternatives. Engineers investigating next-generation battery chemistries consider such mixed-metal oxides to balance cost (iron vs. expensive cobalt), thermal stability, and reversible lithium-ion intercalation capacity.

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.
