A fluoroxalate cathode material for potassium-ion batteries with ultra-long cyclability
The abundance and low cost of potassium makes potassium batteries a promising technology for large scale energy storage. Here the authors apply a previously known frustrated magnet, KFeC2O4F, as the cathode in which the unique structure and Fe2+/Fe3+ redox enable excellent cycling stability.
