· JVASP-40475· Li5Si2BiO8

Li5Si2BiO8 is an experimental lithium-containing ceramic compound combining silicate and bismuth oxide components, developed primarily for solid-state electrolyte and ionic conductor applications in advanced battery research. This material belongs to the family of lithium ion conductors being investigated as alternatives to liquid electrolytes in next-generation lithium-ion and solid-state battery systems. Its potential significance lies in enabling higher energy density, improved thermal stability, and safer battery designs compared to conventional liquid electrolyte technologies, though it remains in early-stage research and is not yet commercialized for production applications.
