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).
Simon Fleischmann and Marco Zeiger are participating at this years installment of the CARBON conference in Melbournce, Australia. Both our PhD students received also a travel fellowship of the German Academic Exchange Organization (DAAD) to cover the conference trip costs. On July 26th, Marco Zeiger is giving a talk called “Designing the carbon/vanadia interface for hybrid electrochemical energy storage” and Simon Fleischmann gives an oral presentation with the title “Carbon onions as substrate/conductive additive for asymmetric vanadia supercapacitor anodes”.
New paper published in ACS Applied Materials & Interfaces on the complementary use of in situ small angle X-ray scattering and electrochemical dilatometry to track the expansion of nanoporous carbon based on hierarchic pore architectures. Our data underline the importance of micropores for the volume changes occuring during electrochemical cycling. This work was in collaboration with Montanuniversität Leoben (Oskar Paris) and Universität Salzburg (Nicola Hüsing).
