I-4 – Ionics in “open” batteries (redox flow batteries)



Organizers: Thomas Zawodzinski (University of Tennessee, Knoxville), Silvia Licoccia (University of Rome "Tor Vergata"), Massimo Guarnieri (University of Padua), Jusef Hassoun (University of Ferrara).

‘Open’ batteries, batteries with redox active species flowing into an active electrode, have excellent potential for low cost and high reliability. This type of storage system includes flow systems such as Redox Flow Batteries (RFBs) or flow capacitors as well as metal-air batteries. At the core of the recent development of such systems is the improvement of the power density of these systems, which are typically implemented as stacks. At the core of many improvements in power density are improvements that lower ionic resistance in the cells. For example, RFBs have been driven by improvements in performance derived from the implementation of new redox active chemicals and of new cell components including electrodes and membranes/separators. Nonetheless, considerations of cost and energy density are driving the continued development in the field. In the case of metal-air systems, the performance of the air electrode is a critical driver.

This symposium will cover the latest developments in high ionic conduction materials for energy production and storage. It is intended to provide a forum to share data and discuss activities on advanced materials and challenges for flow-based energy conversion and storage technologies. Both fundamental and applied aspects of ionic conduction will be included. In this symposium, we propose to explore fundamental and applied aspects of this field. A series of invited speakers will frame the practical application space for redox flow batteries and will be chosen to present innovative material concepts for use in RFBs. This symposium aims at bringing together researchers in materials science, electrochemistry and modeling to highlight recent progresses and discuss challenges and opportunities in the materials aspect research for energy applications.


Abstracts are solicited in, but not necessarily limited to, the following areas:

In this Symposium are also welcome those contributions which cover the topics beyond the above-described areas. This is done to provide the audience with a comprehensive description of Solid State Ionics. If your contribution is difficult to host within the above areas, please do not hesitate to contact directly the Conference Chairmen at ssi21@dii.unipd.it for advice.
