In contrast to the lithium system, the rate performance of TQC in the Zn battery did not show overcharging at higher currents (Fig. ). At the highest current of 10 Ag -1 the system reached Content not peer-reviewed by ChemRxiv. License: CC BY 4.0 a capacity of 114 mAhg -1 (38 % of the maximum capacity) (Fig. ). The comparison of electronic structures of ODQC and TQC obtained with the use of the density functional theory (DFT) computational method, shows a substantial difference between the energy gap of HOMO and LUMO orbital (3.33 eV vs. 2.19 eV vs. 2.26 eV for ODQC, TQC (1) and TQC (2), respectively) suggesting possible higher intrinsic electronic conductivity of TQC (Fig. ).
