| 英文摘要 | the transfer behavior of different ions (v2+, v3+, vo2+, vo2+,h+, so42-) across ion exchange membranes is investigated under vanadium flow battery (vfb) operating condition. vx-20 anion exchange membrane (aem) and nafion 115 cation exchange membrane (cem) are selected to investigate the influence of fixed charged groups on the transfer behavior of different ions. the interaction between different ions and water is discussed in detail aiming to ascertain the variation of different ions in the charge discharge process. under the vfb medium, the transfer behavior and function of different ions are very different for the aem and cem. v2+ ions at the negative side accumulate when vfb is assembled with nafion 115, while the vo2+ ions at the positive side accumulate for vx-20. the so42+ ions will transfer across nafion 115 to balance the charges and the protons can balance the charges of vx-20. finally the capacity fade mechanism of different membranes is investigated, showing that the capacity decay of vfb assembled with nafion 115 mainly results from the cross mix of vanadium ions across the membrane, however, for vx-20, the side reactions can be the major reason. this paper provides important information about electrolyte for the application of vfb.
