· Li2Te

Li₂Te is an inorganic ceramic compound composed of lithium and tellurium, belonging to the family of lithium chalcogenides. While not widely commercialized as a structural ceramic, Li₂Te is primarily studied as a solid-state electrolyte material and ionic conductor in advanced battery research, where lithium-ion transport properties are critical for next-generation energy storage systems. Its potential applications center on all-solid-state batteries and specialized electrochemical devices where high ionic conductivity and chemical stability with lithium metal anodes are advantageous compared to conventional liquid electrolytes.
