Abstract
Cost effective large-scale energy storage mechanisms are of critical importance to our future energy infrastructure consisting of a large portion of renewables and smart-grid. Rechargeable batteries have a great potential to provide a cost-effective energy storage mechanism for this grand demand. We here report on a novel solid oxide iron-air rechargeable battery derived from solid oxide fuel cell (SOFC) and chemical looping hydrogen technologies, featuring a separate energy storage unit and electrode configuration. A systematic study shows that the battery’s capacity and round trip efficiency have strong and competing reliance on how much iron is actually utilized. The energy capacity increases with increasing iron utilization, but at the expense of lowered round-trip efficiency. A practical strategy to operate the new battery is to maintain a low iron utilization of inexpensive iron-based energy storage materials as a mean of achieving required energy/power rating with high efficiency.
