New paper published in ACS Applied Energy Materials on the facile use of free-standing and binder-free hybrid fiber mats composed of vanadium oxide and carbon. The obained electrodes show promising performance for lithium-ion and sodium-ion battery applications.
New paper published in Chemistry – A European Journal on promising strategies to hybridize electrically conductive nanocarbon and metal oxides with high ion intercalation capacity.
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
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.
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.
