New paper published in Journal of Hazardous Materials. This collaborative work explores the degradation of microplastics by electrocoagulation via the combination oxidation and flocculation effects.
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 300 cycles, we observed an average lithium uptake capacity of about 11 mg of Li-ions per 1 gram of active material per cycle. We also demonstrated excellent selectivity toward lithium over competing ions like calcium and cobalt, which is critical in real-world leachates. Our optimized electrode materials and cycling strategies improve both the performance and lifetime of the electrochemical recovery system.

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.
Our Ph.D. student Nikolaos Papadopoulos presents joint work on “Physical Modeling of Silicon-Containing Li-Ion Batteries through a Multi-Species Multi-Reaction Model” as a poster at the Advanced Battery Power in Aachen, Germany.
