· Li4WO5

Li4WO5 is an inorganic ceramic compound composed of lithium and tungsten oxides, belonging to the family of lithium-tungsten mixed-metal oxides. This material is primarily of research interest for energy storage and electrochemical applications, where its ionic conductivity and structural stability at elevated temperatures make it relevant to lithium-ion battery development and solid-state electrolyte systems. Li4WO5 represents an emerging alternative in the quest for improved lithium-conducting ceramics, offering potential advantages in thermal stability and chemical compatibility compared to conventional organic electrolytes, though it remains largely in the development phase rather than widespread industrial production.
