· JVASP-43045· LiTaWO6

LiTaWO6 is a lithium tantalum tungstate ceramic compound that belongs to the family of mixed-metal oxide ceramics. This material is primarily of research interest for applications requiring high ionic conductivity and thermal stability, particularly in solid-state electrolyte and energy storage device development. The combination of lithium with heavy transition metals (tantalum and tungsten) positions it as a candidate material in next-generation battery and electrochemical device research, though it remains less widely deployed in production than established ceramic electrolytes.
