Li₂CN₂ is a lithium-based ceramic compound combining lithium metal with a cyanamide (CN₂²⁻) anion, belonging to the broader class of nitride and nitrogen-containing ceramics. This material remains primarily in the research and development phase, where it is investigated for energy storage applications—particularly as a potential solid electrolyte or anode material for next-generation lithium-ion and all-solid-state batteries due to its ionic conductivity and lightweight lithium content. Compared to conventional oxide-based ceramics, nitrogen-containing lithium compounds like Li₂CN₂ offer opportunities for higher energy density and improved electrochemical performance, though manufacturing scalability and long-term stability in practical devices remain active areas of study.
