| 英文摘要 | in order to reduce the cost of membrane used in vanadium redox flow battery (vrb) system while keeping its chemical stability, nafion/sulfonated poly(ether ether ketone) (speek) layered composite membrane (n/s membrane) consisting of a thin layer of recast nafion membrane and a layer of speek membrane were prepared by chemical crosslink the sulfonic acid groups of different ionomer membranes. scanning electron microscopy (sem) and ir spectra analysis of the membrane showed that nafion layer was successfully deposited on the speek membrane surface and an integral layered membrane structure was formed. the area resistance and permeability of vanadium ions of membrane were also measured. it was found that n/s membrane have a very low permeability of vanadium ions accompanied by a little higher area resistance compared with nafion membrane, as a result, the vrb single cell with n/s membrane exhibited higher coulombic efficiency and lower voltage efficiency compared with vrb single cell with nafion membrane. although n/s membrane delivered relatively lower energy efficiency compared with nafion membrane, its good chemical stability and low cost make it a suitable substitute for nafion membrane used in vrb system.
