| 英文摘要 | In this paper, a series of heteroatom doping graphite felt electrodes are prepared by simple precursor impreg-nation and heat treatment, their application properties as electrode materials for viologen based aqueous organic redox flow batteries (AORFBs) are studied systematically. Elaborate physical, electrochemical characterization and density functional theory (DFT) calculation results indicate that the P-doped GF (P-GF) electrode with higher adsorption energy for viologen molecules, better conductivity and larger electrochemical reactive surface area exhibits better electrochemical performance towards viologen. The charge and discharge performance of the AORFBs with BTMAP-vi as anolyte and Nme-TEMPO as catholyte are investigated to verify the practical appli-cation performance of the P-GF electrode material. The AORFB with P-GF as electrodes shows lower polarization overpotential and higher discharge capacity at different current densities than that using pristine GF as elec-trodes. Specifically, the VE and EE of the BTMAP-vi/Nme-TEMPO AORFBs with P-GF as electrodes are 84.76 % and 82.85 % at the current density of 60 mA cm- 2, 5.34 % and 6.18 % higher than that of the battery with GF as electrodes respectively. After 200 charge and discharge cycles, the capacity retention rate of the P-GF battery increases by more than 20 %, suggesting the better cycle stability. Besides, the peak power density of the P-GF battery achieves 120 mW cm-2, which is much higher than that of the GF battery (85 mW cm-2). The results of this work demonstrate that enhancing the conductivity and adsorption energy of the electrodes should be more effective to improve the performance of viologen based AORFBs, because the electrochemical reactivity of its active electrolytes has been excellent enough. |
