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.

用 φ1'' 实验室尺寸的固体氧化物铁-空气电池演示 10 小时以上的能量存储

具有 10 小时以上循环持续时间的长期电力存储 (LDES) 是一种经济竞争战略,可加速可再生能源向公用事业市场的渗透。不幸的是,没有一种可用的储能技术能够满足 LDES 在持续时间和成本方面的要求。新出现的固体氧化物铁空气电池(SOIABs)以能量密集的固体铁作为储能材料,在 LDES 应用中具有固有的优势。在这里,我们首次报告了 SOIAB 的 LDES 能力,即使在实验室规模也是如此。我们表明具有 Ir 催化的 Fe 床的 SOIAB 可以实现出色的能量密度(625 W h kg -1)、长循环持续时间 (12.5 h) 和在 LDES 相关工作条件下的高往返效率 (~90%)。鉴于出色的低倍率性能以及使用地球上丰富的低成本铁作为储能材料,我们得出结论,SOIAB 是一种非常适合 LDES 应用的电池技术。
