Ion transport across membranes, either synthetic, or derived from biopolymers enables many electrochemical devices and natural phenomena. This includes fuel cells, electrolyzers, redox flow batteries, reverse electrodialysis systems, sensors, the nervous system and metabolism. This symposium will explore the mechanism of ion conduction in polymer electrolyte membranes as a function of morphology and chemistry.

Anion conductors are one of the hottest areas of current development in new materials for electrochemical systems. This symposium will collect researchers from around the world to report recent advances in the synthesis, properties, and device performance of anion exchange membranes and other hydroxide conducting systems – including composite materials. We will have talks on synthesis, new analytical methods and material concepts, and devices that leverage advances in anion conductors. We will pay particular focus to hydroxide conductors and devices that show outstanding performance. With ever increasingly sophisticated instrumentation, we are more able to study polymer morphology and its dynamic dependence on temperature and water or solvent content. Additionally ionic transport can be probed on almost all length scales. Simultaneously, theory and simulation can model ever-larger systems where the size of the simulation box approaches easily measurable length scales.

The aim of this symposium is to bring together polymer scientists, physical chemists, and theoreticians to discuss these concepts in a cross-disciplinary environment. What is needed in this field are new ideas to completely describe ionic transport in complex media. From this a predictive theory of ionic transport in environments particular to the important electrochemical devices under development will allow membranes to be fabricated using advanced design rules to enhance ionic transport. The symposium will also cover the synthesis and characterization of anion-exchange polymeric materials as well as fundamental studies on the conduction mechanisms and the testing of the materials in electrochemical devices.

 

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.
