· JVASP-112446· Li3Fe4CuO8

Li₃Fe₄CuO₈ is a mixed-valent iron-copper lithium oxide ceramic compound representing a complex oxide system relevant to electrochemical and energy storage research. This material family is investigated primarily for lithium-ion battery cathode applications and solid-state electrolyte development, where the mixed transition metal composition (Fe and Cu) offers potential for tuning electronic conductivity and lithium transport. While still largely in research and development rather than widespread commercial production, such lithiated copper-iron oxides are explored as alternatives to conventional layered oxide cathodes due to their potential for improved thermal stability, cost reduction through earth-abundant metal content, and novel electrochemical properties.

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.
