Lithium-mediated nitrogen reduction is a proven method to electrochemically synthesize ammonia; yet the process has so far been unstable, and the continuous deposition of lithium limits its practical applicability. One major problem of further develo

The Haber-Bosch process, which industrially produces ammonia, is one of the most important inventions of the 20th century. It is argued that without the ability to mass produce ammonia and therefore fertilizer, we would not be able to feed half of th
