New paper published in Chemistry of Materials on tailored carbons as substrate for metal oxides

New paper published in Chemistry of Materials on the use of atomic layer deposition (ALD)  to synthesize hybrid electrode materials of tailored mesoporous carbon and vanadium oxide. Using optimized carbon pore structures, pore blocking can be avoided and promising energy storage capacities are enabled for lithium and sodium ion electrolytes.

New paper published in Journal of Physical Chemistry C on in situ electrochemistry of ionic liquids in carbon nanopores

New paper published in Journal of Physical Chemistry C on ion electrosorption of ionic liquids. Using the synergy of electrochemical dilatometry and electrochemical quartz crystal microbalance methodology, important information can be derived. We found that the charging mechanism at low charge is characterized by the exchange of more smaller ions by fewer larger ions. At higher charges, the system is changing to preferred counterion adsorption, which is resulting in a strong increase in the electrode volume. This work was in collaboration with Bernhard Roling from Philipps-Universität Marburg.

New paper on in situ multilength characterization of lithium ion battery composite electrodes published in ACS Applied Materials & Interfaces

New paper published in ACS Applied Materials & Interfaces on in situ electrochemistry. Using electrochemical quartz crystal microbalance methodology, we can discern different mechanical responses of binder materials, such as polyvinyldifluoride or sodium carboxymethyl cellulose. This work was in collaboration with the Aurbach Group at Bar Ilan University, Israel.

New paper published in Sustainable Energy & Fuels on nanoporous carbon beads for supercapacitor electrodes

New paper published in Sustainable Energy & Fuels on the use of the microjet reactor for the synthesis of CDC beads. CDC (carbide derived carbon) was obtained from polymer derived ceramic beads. By adjusting the vinyl / phenyl ratio, the pore size structure was modified. Nanoporous CDC beads showed a high suitability for use as supercapacitor electrodes. This work was in collaboration with Guido Kickelbick (inorganic solid-state chemistry, Saarland University).

New paper published in Journal of Materials Chemistry A on use of MoS2 for high performance electrochemical desalination

New paper published in Journal of Materials Chemistry A on the use of molbdenum disulfide / carbon nanotube electrodes for Faradaic deionization. Our work establishes membrane-free electrochemical desalination with a symmetric cell design that allows energy efficient deionization of saline media of low (5 mM) or high (500 mM) NaCl concentration.

New paper published in Electrochimica Acta on component distribution in lithium titanate / carbon electrodes

New paper published in Electrochimica Acta on the influence of carbon distribution on the electrochemical performance and stability of lithium titanate / carbon electrodes. The carbon distribution is essential to ensure electric conduits throughout the electrode and lack thereof may severely degrade the electrochemical performance stability (not just energy density and power handling).
