I-1 – Beyond lithium batteries: ionic transport in post-Li systems



Organizers: Maximilian Fichtner (Helmholtz Institute), John Muldoon (Toyota research institute of North America), Corsin Battaglia (Swiss federal laboratories for materials science and technology), Federico Bertasi (University of Padua).

Ionic transport in active materials and electrolytes is of paramount importance for the storage of electrical energy and for the function and performance of batteries. There, the ionic mobility in solid active materials eventually decides whether a new material can be suitable for an application, or not. Moreover, solid electrolytes are regarded as a viable and powerful option for making better batteries with regard to storage capacity and safety.


Recently, research activities have grown with the goal to develop viable alternatives to the Li ion battery by using more sustainable materials. In these new electrochemical couples lithium does not necessarily act as charge carrier ion any more. Such “post-Li” systems have the potential to improve safety, to lower the cost and to increase the volumetric energy density in particular. Current objects of study are based on cationic transport of Na+, Mg2+, Ca2+, Zn2+, Al3+, or anionic transport based on F- and Cl-. While there are similarities in the transport mechanism of singly charged Li+ and Na+, the multivalent ions pose additional complexity as their transport is more sensitive to the local geometry and electronic situation of the respective lattice or interstitial site, and of the transition state during hopping. This symposium also welcomes reports on new advancements in concepts, materials, and designs to advance lithium ion battery technology and beyond, including lithium-air, lithium-sulfur, and all solid-state batteries.


The symposium will cover both fundamental and applied aspects of ceramic and polymeric materials that can be used for ionic transport and hosting of the above-mentioned ions. The topics of the symposium include but are not limited to materials synthesis, electrode processing, modeling and simulation, testing and evaluation, characterization and diagnosis. Other topics on electrolytes, safety issues, and characterization techniques are welcome.


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.
