摘要:
合成了磺化聚醚醚酮(SPEEK),以溶液浇铸法制备了磺化聚醚醚酮/聚偏氟乙烯(SPEEK/PVDF)复合膜。详细表征了复合膜的微观形貌、电导率、机械性能等,以SPEEK/PVDF20和SPEEK膜组装的全钒液流电池,并对其性能进行了对比研究。结果表明,PVDF的添加能够有效降低复合膜的吸水率、溶胀度和钒离子渗透率,同时有效提高复合膜的弹性模量和拉伸强度。以SPEEK/PVDF20组装了全钒液流电池,电池的库伦效率为87.35%,电压效率为85.76%,能量效率为74.91%,其综合性能优于纯SPEEK膜组装的电池。
Abstract:
In the present work, the sulfonated polyetheretherketone was synthesized and sulfonated polyetheretherketone/polyvinylidene fluoride(SPEEK/PVDF)composite membranes with different ratios of PVDF were prepared by solution casting method. The micro morphology, conductivity and mechanical properties of the composite membranes were studied in details. The performance of the vanadium redox flow batteries(VRFBs)assembled with the SPEEK and SPEEK/PVDF20 was investigated in details. The vanadium flow battery assembled with SPEEK/PVDF20 showed a coulombic efficiency of 87.35%, a voltage efficiency of 85.76%, an energy efficiency of 74.91%, and its performance was much better than the one assembled with pure SPEEK membrane.
