TLDR
A comprehensive review of the overall development of redox flow battery technology, including proposed chemistries, cell components and recent applications is provided in this paper, where the authors highlight the challenges and directions for further research.Abstract:
Redox flow batteries, which have been developed over the last 40 years, are used to store energy on the medium to large scale, particularly in applications such as load levelling, power quality control and facilitating renewable energy deployment. Various electrode materials and cell chemistries have been proposed; some of the successful systems have been demonstrated on a large-scale in the range of 10 kW–10 MW. Enhanced performance is attributable to the improvements in electrodes, separator materials and an increasing awareness of cell design. This comprehensive review provides a summary of the overall development of redox flow battery technology, including proposed chemistries, cell components and recent applications. Remaining challenges and directions for further research are highlighted.read more

An aqueous, polymer-based redox-flow battery using non-corrosive, safe, and low-cost materials
Tobias Janoschka,Norbert Martin,Udo Martin,Christian Friebe,Sabine Morgenstern,Hannes Hiller,Martin D. Hager,Ulrich S. Schubert +7 more
TL;DR: The polymer-based RFB presented uses an environmentally benign sodium chloride solution and cheap, commercially available filter membranes instead of highly corrosive acid electrolytes and expensive membrane materials, which has an energy density of 10 watt hours per litre, current densities of up to 100 milliamperes per square centimetre, and stable long-term cycling capability.

Recent advances in Redox flow cell storage systems
TL;DR: Several features which were conceived and incorporated into complete redox systems that greatly enhanced its ability to be kept in proper charge balance, to be capable of internal voltage regulation, and in general be treated as a true multicell electrochemical system rather than an assembly of single cells that were wired together, were discussed as mentioned in this paper.

The Influence of Thallium on the Redox Reaction Cr3+/Cr2+
D. Sh. Cheng,E. Hollax +1 more
TL;DR: In this paper, it was shown that the addition of thallium-I-chloride not only accelerates the CrT/CrS reaction in HC1 electrolytes catalytically, using graphite electrodes with small amounts of Au, but also raises th hydrogen overvoltage more than lead and bismuth, the heavy metal catalysts already tested in the practical redox cells.

Modification of Nafion membrane using poly(4-vinyl pyridine) for direct methanol fuel cell
TL;DR: In this article, the authors used poly(4-vinyl pyridine) (P4VP) to reduce the methanol crossover, which causes fuel losses and lower power efficiency, by the formation of an ionic crosslink structure on the Nafion 117 surface.
