Mathias Widmaier has successfully defended his PhD thesis entitled “Improvement of hybrid supercapacitors by optimization of electrode design and material properties”.
There are several contributions of our team at the 69th Annual Meeting of the International Society of Electrochemistry (ISE) in Bologna, Italy. On September 6th, Simon Fleischmann will give an oral presentation entitled “Asymmetric hybrid supercapacitors using molybdenum oxide / carbon nanotube hybrid anodes”, Volker Presser will give a keynote presentation entitled “Water desalination with ion intercalation electrode materials”, and Juhan Lee will give an oral presentation entitled “Faradaic desalination with carbon/metal oxide nanohybrid electrodes”. There will also be two poster presentations: on September 4th, Juhan Lee will present a poster entitled “Potential-dependent, switchable ion selectivity in aqueous media using titanium disulfide”, and on September 5th, Pattarachai Srimuk will present a poster entitled “Potential-dependent, switchable ion selectivity in aqueous media using titanium disulfide”.
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.
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
