Progress on Redox Flow Systems: From Current Technology to Next Generation

Call for Papers

Stationary energy storage systems have increased in relevance over the past few years since they have an important role in grid-scale application such as energy storage from intermittent renewable power sources, smart-grid applications, and electrification in areas with difficult access. Among the various energy storage technologies, the flow-assisted devices (e.g., redox flow batteries, RFB) are proposed to be one of the promising technologies since power output is decoupled from energy capacity and long-cycle life, among others. In spite of these outstanding merits, this technology currently displays some drawbacks, such as low energy density and high cost, in comparison with conventional batteries. Current technologies use metal-redox species (all-vanadium, iron, copper, Zn-air, among others) and need to be further improved in terms of materials and engineering aspects.

In addition to current chemistries and architectures, next-generation flow-assisted systems have been implemented, in detail as follows: (1) organic redox flow batteries (ORFB) are of low cost and are abundant organic molecules instead of traditional metal-redox species and (ii) semisolid flow batteries (SSFB) based on concentrated suspensions have been implemented using intercalation material (i.e., Li or Na).

Therefore, this special issue is aimed at covering the present as well as the next generation of flow-assistant devices in both technologies capacitors and batteries, bringing an overview based on materials, testing evaluation, cell design, modelling and simulation studies, costs, real application, or other contributions developed in the field. All the authors with expertise in these topics are cordially invited to submit their manuscripts to the International Journal of Electrochemistry. Noteworthy high original research papers and review articles covering the current state of the art are welcome.

Potential topics include but are not limited to the following:

  • Latest developments in materials for flow-assisted technologies, including RFB, SSFB, EFC, and other flow-assisted devices
  • Material developments for FAES (formulation of electrolytes/slurries; high performance electrodes, electrocatalyst, and low-cost membrane)
  • Engineering, design, and scale-up of battery architecture
  • Demonstration of flow-assisted energy storage devices for real applications
  • Identifying failure mechanism in flow-assisted energy storage devices
  • Novel methodology for evaluation of FAES performance
  • FAES modelling and simulation
  • Cost analysis, life cycle assessment, and ageing testing

Authors can submit their manuscripts through the Manuscript Tracking System at
