Ammonia production accounts for 1-2% of global greenhouse gas emissions due to its use of the energy intensive Haber-Bosch process, which has been targeted for electrification. Searching for a strategy to facilitate efficient green synthesis of ammonia, lithium-mediated electrochemical ammonia synthesis (LiMEAS) has recently demonstrated promise by consistently achieving current efficiencies above 60% with high ammonia production yields. This LiMEAS approach can be described as a three-step process involving: (i) electrodeposition of lithium onto an electrode (Eq. 1), (ii) formation of a lithium nitride film via nitrogen dissociation (Eq. 2), and (iii) hydrogenation of the nitrogen by a proton donor to release ammonia with the recovery of lithium ions at the end (Eq. 3). The overall reaction is an electrochemical process given by Eq. 4, highlighting lithium's catalytic role.
