· Li2CN2

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.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
