We are grateful that our collaborative review paper (led by Amir Razmjou) obtained the Best Review Paper in Desalination 2023–2025 Award from the Elsevier Journal Desalination.

Our team competed this year again at the International Olympiad in Electrochemical Material Science, which starts to become a bit of a tradition. This year, Energetic People (Stefanie Arnold, Peter Burger, Anna Seltmann) won the 3rd place! 🏅A special thanks to Fyodor Malchik for organizing this amazing event!

We are happy to announce Wensen Wang having received the Humboldt Research Fellowship for Experienced Researchers to carry our research on ion separation! We are excited!

New paper published in ACS Sustainable Chemistry & Engineering. We present a mildly synthesized aluminum layered double hydroxide (Al-LDH) electrode that couples chemical adsorption with electrochemical release to recover lithium at neutral pH, eliminating harsh acids or bases and minimizing secondary pollution. It achieves an average Li+ uptake of 57.6 mg/g with strong Li+ over Na+ selectivity (vs. 1.0 mg/g for commercial Al(OH)₃ over 15 cycles), positioning Al-LDH as a scalable, green candidate for next-generation direct lithium extraction.

Thanks to our collaborators: Chaochao Dun and Oliver Janka.

New paper published in ACS Applied Energy Materials on lithium-sulfur batteries. Our collaborative work explored microporous carbon cathodes with carefully tuned pore sizes, tested in both carbonate- and ether-based electrolytes. Our study shows how pore structure and cathode–electrolyte interphase formation impact cycling stability and sulfur utilization. With optimized microporosity, we achieved over 50 mass % sulfur loading and improved performance in carbonate electrolytes. Thanks to all authors (in order of the manuscript) Delvina Tarimo (PhD), Francisco J. Garcia-Soriano, Alen Vizintin, and Christian Prehal.

New paper published on electrochemical lithium-ion battery recycling in Energy Advances. We demonstrate a sustainable, energy-efficient electrochemical route to recover Li⁺ from spent LFP using carbon-coated LFP electrodes, with NaOH-adjusted electrolytes giving the highest efficiency and an average removal capacity of 18 mg Li per 1 g of LFP over 50 cycles. Capacity fades with prolonged cycling (especially with competing Na⁺ and K⁺) highlighting the need to optimize electrolyte conditions and electrode stability while exploring alternative pH control and scalable designs for circular, low-impact battery recycling.

We are grateful for the Minister to take time to visit the science exhibition ship MS Wissenschaft, anchoring in Saarbrücken, Germany. We discussed climate change, scientific discoveries, basic and applied research – specifically as it pertains to our research on lithium-ion battery recycling.
