The International Nanoscience Student Conference (INASCON) is taking place this year in Trondheim, Norway. On August 8th, Simon Fleischmann gives an oral presentation entitled “Design of carbon/metal oxide hybrids for electrochemical energy storage”. On August 9th, Jaehoon Choi gives an oral presentation entitled “Synthesis and characterization of a nanostructured lamellar vanadium disulfide / carbon hybrid material”.
New paper published in ChemSusChem shows the high desalination performance that can be achieved with the use of lignin-derived activated carbon. Considering the low cost and high availability of lignin, lignin-derived activated carbons are very attractive electrode materials. Our work show the importance to carefully balance the potential and charge of a desalination cell and to carefully consider the intrinsic chemical charge. Only by doing so, we were able to capitalize on the beneficial properties of lignin-derived activated carbon; a “conventional” symmetric cell yielded only a very poor performance instead.
New paper published in ChemSusChem on the use of ion-specific insertion potentials to switch the ion-uptake preference of titanium disulfide. Our proof of concept work exemplifies the switchable preference of titanium disulfide to uptake either Cs or Mg. We expect our concept to be adaptable to many other ionic systems and other electrode materials
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.
