Li3TaO4
ceramic· JVASP-8827· Li3TaO4
Li3TaO4 is an inorganic ceramic compound combining lithium, tantalum, and oxygen, belonging to the family of lithium tantalates and mixed-metal oxides. This material is primarily investigated in research settings for solid-state battery applications, where its ionic conductivity and electrochemical stability make it a candidate for solid electrolytes in next-generation lithium-ion and lithium-metal batteries. Its high density and rigid crystal structure offer potential advantages in energy storage systems requiring mechanical robustness and chemical compatibility with lithium metal anodes, though commercial adoption remains limited compared to more established solid electrolyte materials.

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.
