New paper published in ChemSusChem on lignin-derived carbon for water desalination

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 ACS Applied Materials & Interfaces on molybdenum oxide / carbon hybrids for energy storage

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 on CDI with an aqueous/organic bi-electrolyte

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.
