N2 - Fully organic batteries have been recognised as ideal alternatives to traditional metal-based energy storage devices. However, significant challenges remain in mitigating their low cell voltage and capacity. Here, we construct an all-organic battery based on TEMPO (i.e., 2,2,6,6-tetramethylpiperidyl-1-oxy) radical polymer cathode, poly(TEMPO methacrylate) (PTMA), and conjugated dicarboxylate anode such as silver terephthalate (Ag2TP). Chemical modification of PTMA with aromatic anthraquinone (AQ) results in P(TMA0.95-co-AQ0.05)1610, in which AQ groups facilitate the molecular level binding to CNTs through non-covalent π-π interaction and enhance the charge and mass transport. This fully organic battery delivers a capacity of 182 mAh g−1 based on the anode at 0.5C with an output voltage of 2.8 V. Although the capacity needs further improvement, our work shows the promise of developing high-voltage, fully organic batteries with a judicious electrode design.
