Low Permeability Membrane Regulated by Main/Side-Chain Bisulfonated Polybenzimidazole and CAU-10-H for Vanadium Redox Flow Batteries
Source abstract
Abstract
A series of composite membranes (sPBI p3 -CAU X ) are prepared by using modified sulfonated polybenzimidazole with an optimal side link grafting degree of 30% as a polymer matrix and then doping with CAU-10-H. The hydrophobic alkyl side chains and hydrophilic sulfonic acid groups easily form microphase separated structures due to the polarity difference, which is conducive to the enhancement of proton conductivity. The introduction of CAU-10-H into the polymer effectively prevents the passage of vanadium ions because the vanadium ion transport path becomes more tortuous. The sPBI p3 -CAU 2 membrane has low vanadium permeability (3.1 × 10 –9 cm 2 min –1 ) and excellent ion selectivity (9.16 × 10 6 S min cm –3 ). In addition, the sPBI p3 -CAU 2 membrane shows good cell performance at 60 mA cm –2 with CE of 93.32% and EE of 83.03% compared with those of Nafion 117.
