Pathway toward Scalable Energy-Efficient Li-Mediated Ammonia Synthesis.

Lithium-mediated ammonia synthesis (LiMAS) is an emerging electrochemical method for NH production, featuring a meticulous three-step process involving Li electrodeposition, Li nitridation, and LiN protolysis. The essence lies in the electrodeposition of Li, a critical phase demanding current oscillations to fortify the solid-electrolyte interface (SEI) and ensure voltage stability. This distinctive operational cadence orchestrates Li nitridation and LiN protolysis, profoundly influencing the NH selectivity.
