Abstract

Thirsty battery: We introduce a Li–liquid cathode battery which employs an inexpensive aqueous solution of the Fe3+/Fe2+ redox couple as both cathode and electrolyte. The liquid cathode can be recovered through electric or chemical “charging” after discharge of the battery and, depending on the targeted utilization, can be switched to be operated in either a static or a flow mode.
