摘要
Abstract(#br)We demonstrate that PTCDA is a promising cathode for K-ion batteries with a high capacity of 122<ce:hsp sp="0.25"/>mAh/g at 20<ce:hsp sp="0.25"/>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.
