A proof-of-concept was recently demonstrated in a full cell setup. Key to this process is lithium's ability to dissociate the nitrogen triple bond at near-ambient conditions. This lithium-induced dissociation of nitrogen is a chemical process that is competitive with the hydrogen evolution reaction, the main side reaction leading to low faradaic efficiencies in the system. These advances in activity and selectivity give LiMEAS an advantage over previous electrochemical ammonia synthesis methods which have been plagued by materials design challenges. However, despite the high observed current and faradaic efficiencies from LiMEAS, obstacles remain to improve cyclability and yield. To better understand the LiMEAS system, fundamental investigations into the dynamics of the lithium metal-electrolyte interface are invaluable. This electrochemical interface is reminiscent of the anode in lithium metal batteries, where components of the electrolyte can react with the surface forming a solid-electrolyte interphase (SEI) that has significant impacts on battery performance. In this LiMEAS case, unfavorable interactions with electrolyte components inhibit the reaction of nitrogen with the electrodeposited lithium by slowing, or completely blocking, its diffusion to the surface. Highlighting the parallels between these domains, in batteries, fluorinated solvents were shown to form a favorable SEI composition, whereas for LiMEAS, fluoride-based salts were shown to form uniform SEI interfaces that improved nitrogen transport. Thus, as with lithium metal batteries, several system component interactions may coexist leading to a range in overall performance.
