· JVASP-35936· Li3SmSb2

Li3SmSb2 is an intermetallic ceramic compound composed of lithium, samarium, and antimony, belonging to the family of lithium-based ionic and mixed-valent ceramics. This material is primarily of research interest for solid-state battery applications, particularly as a potential solid electrolyte or anode material, where its ionic conductivity and structural stability at operating temperatures are being investigated. Compared to conventional liquid electrolytes, lithium ceramic compounds offer improved safety, higher energy density potential, and thermal stability, making them candidates for next-generation all-solid-state battery systems in automotive and high-energy-density storage markets.
