· JVASP-31654· Li4TaN3

Li₄TaN₃ is a lithium tantalum nitride ceramic compound belonging to the family of mixed-metal nitrides, currently primarily of research and development interest rather than established in widespread industrial production. This material is being investigated for its potential in solid-state electrolyte and energy storage applications, where its ionic conductivity and chemical stability at elevated temperatures could offer advantages over conventional electrolyte materials in next-generation battery systems. The tantalum-based nitride chemistry positions it as a candidate for high-performance ceramic applications requiring thermal stability and ionic transport properties.
