New collaborative paper (lead: Gündoğ Yücesan) published in ACS Nano. We have developed a new nickel–vanadium phosphonate framework that combines redox-active metal centers with a chemically robust layered structure for aqueous energy storage. The material remains stable from pH 2 to 10, delivers up to about 300 F/g under slow-scan conditions, and retains its performance […]
New collaborative paper published in Macromolecular Rapid Communications. In this study, we demonstrate a particle-templating strategy to create hierarchically porous, chemically functional coatings on cellulose fibers. Silica-polymer core-shell particles are deposited on cellulose paper and subsequently etched to generate porous polymer coatings with tunable surface chemistry, including hydroxy and epoxy groups. This approach opens new […]

New paper published in Water Research in collaboration with Helmholtz Centre for Environmental Research (Navid Saeidi & Anett Georgi). Electrosorption is an emerging approach for removing and concentrating trace organic contaminants from water, including PFAS and pharmaceuticals, by combining conductive adsorbents with electrical control. This Making Waves article argues that such systems should not simply […]
In a new collaborative paper in Advanced Functional Materials, we report an exfoliation-induced electrochemical reconstruction strategy that transforms CuCoAl layered double hydroxides into an amorphous/crystalline heterostructure for efficient nitrate reduction to ammonia. The reconstructed catalyst combines metallic Cu, crystalline Co(OH)2, and amorphous CoOOH, enabling high ammonia selectivity, excellent Faradaic efficiency, and strong cycling stability. Beyond […]
Prof. Dr. Volker Presser has been elected Fellow of the International Society of Electrochemistry (ISE).

New collaborative work with University of Granada (Silvia Ahualli) published in RSC Energy Advances. This study explores an electrochemical route for selective lithium recovery from saline water using lithium manganese oxide, whose spinel structure can reversibly intercalate lithium ions under controlled cell voltages. By combining lithium manganese oxide with polyelectrolyte coatings, the work links ion […]
New paper published on electrochemical Li-ion extraction in the context of lithium-ion battery recycling in ChemSusChem. In this collaborative work with Fachhochschule Münster, we demonstrate an electrochemical route to recover lithium ions directly from real battery recycling process water generated during the wet shredding of lithium iron phosphate batteries. Using an LFP-based selective desalination cell, […]

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 […]
Anna Seltmann and Stefanie Arnold presented work at the 13th EEIGM International Conference on Advanced Materials Research (AMR) in Nancy, France. Anna Seltmann presented a poster with the title “Ionic Liquids as Electrolytes in Supercapacitors” and Stefanie Arnold gave a talk on “Hybrids for Electrochemical Technologies: From Batteries to Desalination and Closed-Loop Recycling”.
Welcome new student intern Matthew Lowesome, who will be working on next-generation battery materials and technology 🔋
New collaborative paper published in RSC Energy Advances. This study addresses one of the central challenges of lithium-sulfur batteries: capacity fading caused by polysulfide migration and incomplete confinement in carbon hosts. The team engineered a microporous carbon with a pore size of about 1.2 nm to host both short- and long-chain polysulfides, then further tuned […]
Anna Seltmann, Nicolas Huth, and Volker Presser were involved with the 116th 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 […]
New paper published in EES Batteries on the electrochemical modeling of silicon in lithium-ion batteries. In cooperation with industry partners and modelling experts, we presents a new electrochemical modeling framework for silicon anodes in lithium-ion batteries, capturing key challenges such as voltage hysteresis, phase transformations, and long relaxation processes. By combining multi-species, multi-reaction modeling with […]
Anna Seltmann and Nicolas Huth represent our team and outline our team’s profile at the TraWeBa event “Trendsetter Battery“.
New collaborative paper published in Battery Energy on “Intraparticular inhomogeneity limits capacity in lithium sulfur batteries with carbonate electrolyte”. This work shows that the performance of lithium-sulfur batteries with carbonate electrolytes is strongly governed by how the cathode-electrolyte interphase (CEI) forms inside nanoporous carbon host particles during the first discharge. Using cryogenic electron microscopy together […]
