As tradition over the last almos 15 years, our team presents our work at the Ph.D. day of Saarland University. This year, we had the following presenters:

Peter Burger:  Electrochemical lithium-ion recovery from battery recycling process water

Jean Gustavo de Andrade Ruthes:  Electrochemical Behavior of metal and covalent organic frameworks – toward tunable redox-active materials

Cansu Kök:  Composite membrane-based lithium-ion extraction from brines and seawater

Liying Xue:  Hierarchical MoO₂/Mo₂C nanoflowers for lithium-ion batteries anodes

Anna Seltmann, Nicolas Huth, and Volker Presser were involved with the 116^th MNU Federal Congress of the German Association for the Promotion of Mathematics and Science Education in Saarbrücken, Germany.

Volker Presser gave a seminar talk with the title “Quo vadis BatterienMythen, Fakten und Entwicklung”.

Anna and Nicolas provided a hands-on workshop to build your own battery (BYOB) to create (and test) functional coin cells.

Nikolaos Papadopolous gives an oral presentation at the 22^nd Symposium on Modeling and Experimental Validation
of Electrochemical Energy Technologies (ModVal 2026) in Lausanne, Switzerland. The presentation has the title “Electrochemical Modeling of Silicon in Lithium-Ion Batteries Using a Multi-Species, Multi-Reaction Framework with Atomistic Insights”.

Two oral contributions to the DLE Symposium in Karlsruhe, Germany, from our team:

Cansu Kök: Tailored MXene electrodes for selective and stable electrochemical lithium recovery in aqueous solutions (oral)

Stefanie Arnold: Electrochemical perspectives for Li-ion battery recycling (oral)

Liying Xue presents a poster on our work on multi-component composition materials at the at the Faraday Discussion on “High-entropy alloy nanostructures: from theory to application” by the Royal Society of Chemistry (RSC) in London (UK). Thanks to our external collaborators Chaochao Dun and Oliver Janka!

An annual tradition: our team at the PhD students’ day of Universität des Saarlandes 🎓

Cansu Kök answered the question on how to design electrochemical tools for the direct lithium-ion separation from seawater (and Saarland mine water): “Continuous lithium-ion extraction via fuel cell desalination”; work in collaboration with Lei Wang, Jean Gustavo De Andrade Ruthes, Antje Quade, and Matthew Suss.

Nikolaos Papadopoulos presented his inspiring modelling + experimental work on “Physical modeling of silicon-containing Li-ion batteries through a multi-species multi-reaction model” to design high-performance Si-based lithium-ion batteries; work in collaboration with Oliver Queisser and Simon Schwunk.

Liying Xue presented the power of multi-phase material design on high-capacity lithium-ion batteries: “Multi-phase synergy enhances lithium storage performance of oxalate”; work in collaboration with Oliver Janka and Chaochao Dun.

Volker Presser gives two oral presentations at the MATSUS conference in Sevilla, Spain:

• NEMX25 Symposium: MXene and hybrid electrodes for high performance energy storage (March, 3^rd)
• ELECTROWAT25 symposium: Electrochemical Lithium-ion separation (March, 5^th)

Two contributions from our team at the 38^th Topical Meeting of the International Society of Electrochemistry (Nanomaterials in Electrochemistry): Volker Presser is giving an oral presentation with the title “MXene and hybrid electrodes for high performance energy storage” and Cansu Kök present a poster on “Continuous Lithium-Ion Extraction via Fuel Cell Desalination”.
