Composite sPEEK Membranes for Vanadium Redox Batteries Application
Procedia Engineering, 2012 Composite sPEEK membranes having different sulphonation degree were realised by using different percentages (0-20wt.%) of a functionalised silica (3-aminopropyl-functionalised silica) as a filler for vanadium redox batteries applications (VRBs). The prepared membranes were characterised in terms of Ion Exchange Capacity (IEC), vanadium up-take, proton ...
