The so-called lithium redox-mediated nitrogen reduction reaction presents the only known process enabling genuine electrochemical conversion of N2 to ammonia. Notwithstanding the rapidly increasing investigative efforts, the commonly reported performances of the Li-mediated N2 electroreduction, viz. yield rate, current-to-ammonia (faradaic) efficiency and durability in operation, still pertain to the domain of academic research rather than practical development. Our most recent work focused on redesigning the key components of the electrolytic N2 reduction cell enabled breakthroughs in all the key metrics of the process. Specifically, we have introduced a stable proton shuttle based on the phosphonium cation that delivers protons to…
