· Li4 Sm4 O8

Li₄Sm₄O₈ is an oxide ceramic semiconductor composed of lithium and samarium oxides, belonging to the family of rare-earth lithium compounds. This material is primarily investigated in research contexts for solid-state ionics and energy storage applications, where its ionic conductivity and structural stability make it a candidate for solid electrolytes in next-generation lithium-ion batteries and fuel cells. Compared to conventional liquid electrolytes, lithium rare-earth oxides offer improved thermal stability, wider electrochemical windows, and reduced flammability, though most compositions in this family remain in development rather than high-volume production.

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.
