Graphene oxide (GO) has attracted tremendous attention in membrane-based separation field as it can filter ions and molecules. Recently, GO-based materials have emerged as excellent modifiers for vanadium redox flow battery (VRFB) application. Its high mechanical and chemical stability, nearly frictionless surface, high flexibility, and low cost make GO-based materials as proper materials for the membranes in VRFB. In VRFB, a membrane acts as the key component to determine the performance. Therefore, employing low vanadium ion permeability with excellent stability membrane in vanadium electrolytes is important to ensure high battery performance. Herein, recent progress of GO-modified membranes for VRFB is briefly reviewed. This review begins with current membranes used for VRFB, followed by the challenges faced by the membranes. In addition, the transport mechanism of vanadium ion and the stability properties of GO-modified membranes are also discussed to enlighten the role of GO in the modified membranes.

A series of sulfonated polyimides (SPIs) were synthesized by 1,4,5,8-naphthalene tetracarboxylic dianhydride (NTDA), 2,2′-benzidinedisulfonic acid (BDSA) and 4,4′- diaminodiphenyl ether (ODA) in m-cresol. The sulfonation degree of SPI was controlled through the ratio of sulfonated diamine to the non-sulfonated diamine, and the SPI membranes were prepared by a casting method. The chemical structures of SPI membranes were characterized by FT-IR. The properties of obtained SPI membranes were investigated, such as water uptake, ion exchange capacity, proton conductivity and permeability of vanadium ion. The proton conductivities of SPI membranes are ranged from 0.012 to 0.051 S/cm, and the permeabilities of vanadium ion are one or two orders of magnitude less than that of Nafion®117 (1.80×10-6cm2/min ). Experimental results showed that SPI membranes are potential candidates for vanadium redox flow battery.

Simplified Mathematical Model

All-vanadium redox flow battery is one of the promising rechargeable battery since it is able to withstand average loads, high energy efficiency and high power output. The battery exhibits the excellent transient behaviour and sustains sudden voltage drop. The dynamics of the battery is governed by the conservation equations of mass and charge. The simplified mathematical model includes major resistances, electrochemical reactions and recirculation of electrolyte through reservoirs. The mathematical model is able to predict the performance of the battery. The cell performance can be increased by increasing the concentration of the vanadium ions, the flow rate and the temperature inside the cell. The model results are validated with the available experimental result which shows better agreement.
