ESPE23 – European Symposium & Workshop on Polymer Electrolytes for Battery Applications


Polymer electrolytes have a long history in battery research and both material development and our fundamental understanding of ion transport mechanisms in polymers has evolved with it. Today, we are standing at the crossroads overseeing many possible winding paths down battery lane with a multitude of battery technologies to choose from. Diversification in many different cell chemistries opens new avenues to explore and encourages to revisit some concepts and findings of past days.

The pandemic has made it difficult for our community to meet and exchange, which has become clear during the International Symposium of Polymer Electrolytes (ISPE17) in Canada in October 2022. While we remain dedicated to other international communities, not least the ISPE, we, the Organizers, feel that a more limited meeting in terms of scope and geographical target group would be highly appreciated. It is our ambition to assemble primarily the European academic research community in this area, including a large number of PhD students, other newcomers, together with relevant researchers from industry, this year at the Karlsruhe Institute of Technology (KIT) in Germany for the first European Symposium on Polymer Electrolytes for Battery Applications (ESPE23) hosted from September 25th to 27th 2023.

We would like to give newcomers to the field the opportunity to meet leading experts, present their latest results, network and find new colleagues and friends to advance the development of polymer electrolytes together. Furthermore, we would like to encourage PhD students of our Center of Electrochemical Energy Storage (CELEST) as well as our research Cluster of Excellence for post-Li storage (POLiS) to join this meeting in the framework of a workshop module of the Graduate School of Electrochemical Energy Storage (GS-EES) to get in touch with the latest trends and advances in this exciting area.

We hope to see many of you this September in Karlsruhe!

ESPE23 will take place at KIT Campus South directly in central Karlsruhe nearby the Karlsruhe castle. The university campus can be readily reached on foot or by tram (stop “Durlacher Tor / KIT” or “Kronenplatz”). The event will be hosted in NTI (faculty of Communications Technology) lecture hall in building 30.10, room 030 (ground floor). A campus plan can be found here: (searchable by building and faculty).


Karlsruhe Institute of Technology
Kaiserstraße 12
76131 Karlsruhe


By car: You can find a comprehensive summary of how to get to KIT on the following link:

By plane: The closest airport is Baden Airport, near Baden-Baden, with a number of low budget connections from all over Europe arriving daily. There are bus connections from the airport directly to Karlsruhe or nearby train stations to hop on one of the commuter trains to the city. Frankfurt Airport (FRA) is just an hour away from Karlsruhe by ICE train (either with a stopover or a change of trains in Mannheim). There are two trains leaving hourly from FRA to Karlsruhe and vice versa. We recommend to book a “flexible ticket (FlexTicket)” in advance (visit, so you can hop on any train towards Karlsruhe. Another option, somewhat further away is Stuttgart Airport. From the airport there are commuter trains to Stuttgart main station. There are several trains leaving to Karlsruhe every hour. The train ride takes about 1h. 

By train: Karlsruhe main station (Karlsruhe Hbf) is located in the city centre and is a hub that can be readily reached from several surrounding airports (Frankfurt ca. 1h, Baden Airport ca. 1h, Stuttgart, 1.5-2h) or by international trains from Basel SBB (Switzerland), Brussels, Munich or Paris.
