· Li4 W1 O5

Li₄WO₅ is an inorganic ceramic compound containing lithium, tungsten, and oxygen, belonging to the family of mixed-metal oxides with potential semiconductor or ionic-conductor properties. This material is primarily of research interest rather than established industrial production; it is investigated for energy storage applications (particularly solid-state battery electrolytes and lithium-ion conductors) and potentially for photocatalytic or optoelectronic applications due to its mixed-valence composition. The tungsten-lithium oxide system is notable for exploring new ion-transport mechanisms and crystal structures that could outperform conventional lithium ceramics in thin-film or all-solid-state battery architectures.

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.
