A recent report described an innovative rechargeable metal-nitrogen battery based on a graphene-supported palladium cathode and a polished aluminum anode interfaced with an ionic liquid electrolyte comprised of aluminum chloride/1-butyl-3-methylimidazolium chloride. Remarkably, the aluminum-nitrogen battery was demonstrated to serve the dual purpose of both storing and retrieving energy and having the ability to fix the nitrogen stream as ammonia.
