Potassium-ion batteries are a compelling technology for large scale energy storage due to their low-cost and good rate performance. However, the development of potassium-ion batteries remains in its infancy, mainly hindered by the lack of suitable cathode materials. Here we show that a previously known frustrated magnet, KFeC<sub>2</sub>O<sub>4</sub>F, could serve as a stable cathode for potassium ion storage, delivering a discharge capacity of ~112 mAh g<sup>-1</sup> at 0.2 A g<sup>-1</sup> and ...[more]
