Here we report a room-temperature sodium metal battery, where the sodium initially stored in a Na 3 V 2 (PO 4 ) 3 cathode is plated, upon charging, onto an aluminum current collector coated with a thin nucleation layer. To maximize the battery performance, conventional sodium-ion anode materials, in...
