Abstract
We here demonstrate that the iron derived from an iron-based metal-organic framework (MOF), with exposed high-density Fe-atom planes, exhibits improved reduction activity, enabling good rechargeability of solid oxide iron-air redox batteries at 500 °C. The discharge mass specific energies are 226.5 W h kg-Fe and 214.8 W h kg-Fe at C/4 and C/3, respectively, at a constant Fe-utilization of 20%.
摘要
我们在此证明，源自具有暴露的高密度铁原子平面的铁基金属有机框架（MOF）的铁表现出更高的还原活性，使得固体氧化物铁空气氧化还原电池在500℃时具有良好的可再充电性。在20%的恒定铁利用率下，C/4和C/3时的放电质量比能量分别为226.5 W h kg-Fe和214.8 W h kg-Fe。
