英文摘要: Sulfonated poly(tetramethydiphenyl ether ether ketone) (SPEEK) with various degree of sulfonation is prepared and first used as ion exchange membrane for vanadium redox flow battery (VRB) application. The vanadium ion permeability of SPEEK40 membrane is one order of magnitude lower than that of Nation 115 membrane. The low cost SPEEK membranes exhibit a better performance than Nation at the same operating condition. VRB single cells with SPEEK membranes show very high energy efficiency (>84%), comparable to that of the Nation, but at much higher columbic efficiency (>97%). In the self-discharge test, the duration of the cell with the SPEEK membrane is two times longer than that with Nation 115. The membrane keeps a stable performance after 80-cycles charge-discharge test. (C) 2010 Elsevier B.V. All rights reserved.
