· Li4 O4 Cu4

Li4O4Cu4 is a quaternary lithium copper oxide ceramic compound that functions as a semiconductor, combining lithium and copper oxides in a mixed-valence system. This material belongs to the family of lithium-based transition metal oxides, which are primarily of research interest for energy storage and catalytic applications rather than established industrial production. The compound's potential lies in battery chemistry (particularly as a cathode material or electrolyte component), solid-state ionic conductivity, and catalysis research, where the synergistic properties of lithium and copper oxides—such as lithium-ion mobility and copper's redox activity—make it relevant to next-generation energy devices and electrochemical systems.

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.
