Welcome visiting PhD student Jemma Rowlandson

Welcome new visiting PhD student Jemma Rowlandson from Valeska Ting‘s team at the University of Bristol, UK! Jemma will be working on bio-derived nanoporous carbons for electrochemical applications in the next 3 months. See also Jemma’s fantastic YouTube science videos (video 1 / video 2 / video 3).

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, […]

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 […]

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 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).
