Abstract

A free-standing PTCDA/RGO film was synthesized by an ultrasonication-aided self-assembly strategy to alleviate the solubility of PTCDA in organic electrolytes. The PTCDA/RGO-50% film cathode exhibits a high capacity of 135.1 mA h g^-1 at 0.05 A g^-1 and excellent cycling stability (capacity retention of 85% after 200 cycles) for potassium ion batteries.
