Nicolas Jäckel has successfully defended his PhD thesis entitled “Structure and properties of supercapacitor and lithium-ion battery electrodes: The role of material, electrolyte, binder, and additives”.
New paper published in ACS Applied Materials & Interfaces on molybdenum oxide / carbon hybrids for energy storage. Using atomic layer deposition, our work highlights the importance of nanoscale material engineering to yield an optimized performance of hybrid lithium ion capacitors. This work was in collaboration with the INP Greifswald, which is a sister Leibniz institute.
Welcome new group members Marc Schmidt, Maike Ulbricht, and Yuan Zhang! Ms. Ulbricht and Mr. Schmidt are our new student interns from Saarland University. Ms. Zhang starts as a PhD student working on Faradaic materials and has a master’s degree from Ulm University.
New paper published in Desalination moves our concept of concentration-gradient membrane CDI to a new level: by using an organic electrolyte in one compartment of a 3-channel setup, it is possible to operate the electrode in that compartment at an electrode potential much higher than for an aqueous electrolyte. Thereby, a high desalination capacity of more than 60 mg/g NaCl can be achieved at a stable cell voltage of 2.4 V.
New article published in Journal of Materials Chemistry A on the use of optimized anatase titanium dioxide / carbon onion hybrid electrodes for lithium-ion batteries with enhanced charge storage performance.
New article published in Chemistry – A European Journal on the synthesis and application of gyroidal titania/carbon hybrid electrodes for lithium-ion anodes with high areal an volumetric capacity.
This year, we have to oral presentations at the Annual Spring Meeting of the Materials Research Society (MRS) in Phoenix, USA. Simon Fleischmann gives a talk entitled “Tailored Mesoporous Carbon/Vanadium Pentoxide Hybrid Materials for Pseudocapacitive Lithium and Sodium Intercalation” on April 3rd. This work was in collaboration with Lars Borchardt (TU Dresden). Aura Tolosa gives a talk entitled “Hybrid titanium-niobium oxide/carbon electrospun nanofibers as lithium-ion battery electrodes” on April 6th.
New paper published in ACS Sustainable Chemistry & Engineering on the use of molybdenum carbide MXene with divacancy ordering for the effective desalination of brackish water and sea water. This work also provides the first chemical online monitoring evidence of anion intercalation in MXene and extends the use of 2D intercalation materials for the desalination of brackish water to seawater concentrations. The material synthesis was developed and carried out by our research collaborators at Linköping University, Sweden (Johanna Rosen).
