Abstract

© 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim The energy and power density of conventional batteries are far lower than their theoretical expectations, primarily because of slow reaction kinetics that are often observed under ambient conditions. Here we describe a low-cost and high-temperature rechargeable iron–oxygen battery containing a bi-phase electrolyte of molten carbonate and solid oxide. This new design merges the merits of a solid–oxide fuel cell and molten metal–air battery, offering significantly improved battery reaction kinetics and power capability without compromising the energy capacity. The as-fabricated battery prototype can be charged at high current density, and exhibits excellent stability and security in the highly charged state. It typically exhibits specific energy, specific power, energy density, and power density of 129.1 Wh kg−1, 2.8 kW kg−1, 388.1 Wh L−1, and 21.0 kW L−1, respectively, based on the mass and volume of the molten salt.
