In summary, we presented a novel high-performance organic cathode material obtained with a facile two-step synthesis from commercially available precursors. In the OTQC-Li battery, newly synthesized OTQC material delivered a specific capacity of 327 mAhg -1 at 50 mAg with an average voltage of 2.63 V, corresponding to one of the highest reported energy densities for redox-active organics of 860 Whkg -1 on the material level Furthermore, the material demonstrated excellent cycling stability having capacity retention of 82 % after 400 cycles at 50 mAg -1 , which decreased to 77 % after 800 cycles at a high current of 1 Ag -1 . By excluding Content not peer-reviewed by ChemRxiv. License: CC BY 4.0 limitations of Li metal anode a symmetric cell approach and OTQC-LTO cell testing enabled to find excellent cycling stability of OTQC electrodes at high current densities. Increased performance in comparison with TQC was also observed in the OTQC-Zn battery where it exhibited a specific capacity of 326 mAhg -1 with an average voltage of 0.86 V at 100 mAg -1 , but showed worse cycling stability reaching 42 % after 400 cycles. We believe that the high theoretical capacity of OTQC material and the excellent practically demonstrated electrochemical stability of the corresponding electrodes present a definite motivation for further improvements of synthesis approaches and electrode engineering efforts on the path to reach reliable high-energy battery systems.
