| 英文摘要 | perfluorosulfonic acid ionomers (pfsi) with different side-chain lengths have been investigated with respect to their morphology and electrochemical properties in vanadium flow batteries (vfb). the results indicated that the membrane with the shortest side chains (ssc-m2) displayed small ion clusters and a low degree of hydrophobic-hydrophilic separation, which is favourable to reduce the cross-over of vanadium ions in the vfb. ssc-m2 shows a similar proton conductivity to nafion, which carries longer ionic side chains but with much lower ion permeability. as a result, the vfb assembled with ssc-m2 exhibited a superior coulombic efficiency and a voltage efficiency close to that of nafion115. insitu mass transfer revealed that ssc-m2 had a remarkably low degree of vanadium and water transfer across the membrane, which resulted in lower capacity fading than in the case of nafion115. these results indicate that a membrane with short side chains is an ideal option in the fabrication of high-performance vfbs with low capacity loss. |
