具有10小时以上循环持续时间的长时间电力存储（LDES）是一种具有经济竞争力的战略，可以加速可再生能源向公用事业市场的渗透。不幸的是，现有的储能技术在持续时间和成本方面都无法满足LDES的要求。以高能量密度的固体铁为储能材料的固体氧化物铁空气电池（SOIABs）在LDES应用中具有固有的优势。在这里，我们首次报告的LDES能力的SOIABs，即使在实验室规模。我们表明，SOIAB与Ir催化的铁床可以实现优异的能量密度（625 W h kg−1），长循环时间（12.5 h）和高往返效率（12.90%）下LDES相关的工作条件。鉴于出色的低倍率性能和使用地球丰富，低成本的铁作为储能材料，我们得出结论，SOIAB是一个非常适合的电池技术LDES应用。
Long duration electricity storage (LDES) with 10+ hour cycle duration is an economically competitive strategy to accelerate the penetration of renewable energy into the utility market. Unfortunately, none of the available energy storage technologies can meet the LDES requirements in terms of duration and cost. The newly emerged solid-oxide iron–air batteries (SOIABs) with energy-dense solid iron as an energy storage material have inherent advantages for LDES applications. Herein, we report for the first time the LDES capability of SOIABs even at a laboratory scale. We show that SOIABs with an Ir-catalyzed Fe-bed can achieve excellent energy density (625 W h kg−1), long cycle duration (12.5 h) and high round-trip efficiency (∼90%) under LDES-related working conditions. Given the excellent low-rate performance and the use of earth-abundant, low-cost Fe as an energy storage material, we conclude that the SOIAB is a well-suited battery technology for LDES applications.
