New paper published in ACS Applied Energy Materials on nanoporous carbon electrodes for lithium-sulfur batteries

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 % […]

New paper published on electrochemical lithium-ion battery recycling in Energy Advances

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 […]

New paper published in Journal of Power Sources on free-standing rGO/NiHFC films for energy storage

New collaborative paper (Victor H. R. Souza) published in Journal of Power Sources. To support the energy transition, we developed freestanding electrodes combining reduced graphene oxide, polyaniline, and nickel hexacyanoferrate (NiHCF), which is a promising material for aqueous batteries due to its long cycle life and redox-active structure. These rGO/PAni/NiHCF films achieve high specific capacities […]

Annual group retreat

We enjoyed our annual group retreat – due to a booking issue, reduced to one day, but no less fun! We enjoyed our group dinner, as won by popular vote, in the Vietnamese restaurant Yoko in Saarbrücken. For the scientific talks, we mixed things up: rather than all Ph.D. students and Postdocs presenting theirworks… each […]

New paper published in Separation and Purification Technology on the electrochemical recovery of lithium-ions from spent battery cells

New paper published in Separation and Purification Technology on “Optimized electrochemical recovery of lithium-ions from spent battery cells using carbon-coated lithium iron phosphate”. We optimized a system based on carbon-coated lithium iron phosphate electrodes. The electrodes selectively extract lithium ions from complex leaching solutions derived from real LCO (LiCoO₂) cathode materials. Over the course of […]

New paper published on transparent MXene/polymer thin film supercapacitors in Electrochimica Acta

New paper published in Electrochimica Acta on “Transparent polyaniline/MXene thin films supercapacitors”. In this collaborative work, we developed transparent, nanostructured films combining MXene Ti3C2Tx and polyaniline for miniaturized energy storage devices. The films show promising electrochemical performance and stability, opening avenues for transparent supercapacitor applications. Co-authors: Ariane Schmidt, Samantha Husmann, and Aldo J.G. Zarbin.
