context: Recently, Fan and co-authors proposed a PTCDI derivative with anthraquinone moieties (PTCDI-DAQ 11). This compound has lower solubility than PTCDI due to the increased molecular weight, as well as higher theoretical capacity of 200 mA h g−1. The observed Qm was up to 220 mA h g−1, again higher than the theoretical value. A decent capacity retention of 73% was demonstrated in the electrolyte with relatively low salt concentration (1 M KPF6 in DME). Moreover, a remarkable capacity of 137 mA h g−1 was obtained at 20 A g−1. A full cell with pre-potassiated terephthalate (K4TP) anode had a high energy density of 295 W h kg−1 (213 mA h g−1 × 1.38 V, calculated per cathode mass), excellent rate capabilities (94 mA h g−1 at 10 A g−1), and cycling stability (49% and 32% retention after 10000 and 30000 cycles, respectively).
