A sulfonated poly(arylene ether ketone)/polyoxometalate-graphene oxide composite: a highly ion selective membrane for all vanadium redox flow batteries.
Md Abdul AzizKwangjin OhSangaraju ShanmugamPublished in: Chemical communications (Cambridge, England) (2018)
A highly ion-selective membrane for vanadium redox flow batteries (VRBs) consisting of sulfonated poly(arylene ether ketone) (SPAEK) and polyoxometalate coupled with a graphene oxide was designed and fabricated. The SPAEK/PW-mGO composite membrane showed an effectively low self-discharge rate and excellent Coulombic efficiency (98.73%) in VRBs.
