Cation dependent resistance of a commercial cation exchange membrane, Nafion™ 212, as well as the solubility of select active materials are investigated, demonstrating practical consequences of cation.
What are redox flow batteries?
Provided by the Springer Nature SharedIt content-sharing initiative Redox flow batteries are a critical technology for large-scale energy storage, offering the promising characteristics of high scalability, design flexibility and decoupled energy and power.
Are aqueous Zn–Mn flow batteries suitable for large-scale energy storage?
Aqueous Zn–Mn flow batteries (Zn–Mn FBs) are a potential candidate for large-scale energy storage due to their high voltage, low cost, and environmental friendliness. However, the unsatisfactory performance due to the sluggish MnO2 reduction reaction (MnRR) kinetics leads to low discharge voltage (typically Recent Open Access Articles
Are redox flow batteries sulfonate-functionalized?
Redox flow batteries using synthetically tunable and resource abundant organic molecules have gained increasing attention for large-scale energy storage. Herein we report a sulfonate-functionalized...
How redox chemistry has evolved in flow batteries?
From the zinc-bromide battery to the alkaline quinone flow battery, the evolution of RFBs mirrors the advancement of redox chemistry itself, from metal-centred reactions to organic molecular designs 57. A range of novel redox species and design concepts have been proposed and developed for next-generation flow batteries in recent years.
The authors declare no conflict of interest. Abstract Redox flow batteries show promise for large-scale grid stabilisation. Of these, organic redox flow batteries (ORFBs) harbour the potential for sustainable and economic operation due to the...
Here, we present an ultra-ion-selective SPEEK-SX membrane, it enables 600 cycles at 160 mA cm −2 with only 0.00935% per cycle capacity decay, outperforming Nafion-212, offering a fluorine-free alternative. Redox flow batteries show promise for large-scale grid stabilisation.
