A Fe-thiolate layered metal organic framework as a high-performance electrode material for potassium-ion batteries
Here, we report a rare example of an Fe-based MOF capable of accommodating K<sup>+</sup> ions electrochemically within its layered framework, achieving low polarization, high capacity utilization (∼0.8 electrons exchanged per Fe), and stable cycling performance. <i>In situ</i> Mössbauer spectroscopy and <i>operando</i> XRD analyses revealed that the observed electrochemical storage arises from the Fe<sup>3+</sup>/Fe<sup>2+</sup> redox couple with polyphasic transformations.
