We demonstrate that PTCDA is a promising cathode for K-ion batteries with a high capacity of 122 mAh/g at 20 mA/g and moderate rate and cycling performance. Upon potassiation, PTCDA crystals experience a high level of amorphization, while upon depotassiation, the crystal structure is partially restored, revealed ex situ XRD and IR. (C) 2015 Elsevier B.V.
