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.

Two contributions at the ISE conference in Providence

There are two contributions with our work at this year’s Annual Meeting of the International Society of Electrochemistry. On August 29th, Juhan Lee is giving an invited oral presentation wiht the title “Redox-enabling nanoporous carbons for high-performance energy storage” and collaborator Bastian Etzold (TU Darmstadt) is giving an oral talk on “Core-shell carbide-derived carbons as platform for high performance electrochemical energy storage and electrocatalysis”.

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.

Collaborator Christian Prehal presents joint work at the IMRC in Cancun

Christian Prehal from the Institute of Physics at Montanuniversität Leoben (Austria) is presenting joint work on in situ tracking of ion electrosorption in nanoporous carbon at the XXVI International Materials Research Congress (IMRC) in Cancun, Mexico. The invited lecture is entitled “Structure and kinetics of ions in nanoporous carbon supercapacitors studied by in situ X-ray scattering and atomistic modelling”.
