A Roadmap for Solid-State Batteries
Schmaltz, Thomas; Hartmann, Felix; Wicke, Tim; Weymann, Lukas; Neef, Christoph; Janek, Jürgen (2023)Solid-state batteries are considered as a reasonable further development of lithium-ion batteries with liquid electrolytes. While expectations are high, there are still open questions concerning the choice of materials, ... -
Amorphous and highly nonstoichiometric titania (TiOx) thin films close to metal-like conductivity
Leichtweiss, Thomas; Henning, Ralph A.; Koettgen, Julius; Schmidt, Rüdiger M.; Holländer, Bernd; Martin, Manfred; Wuttig, Matthias; Janek, Jürgen (2014)Oxygen-deficient titanium oxide films (TiOx) have been prepared by pulsed laser deposition at room temperature. Samples in their as-deposited state have an average composition of TiO1.6, are optically absorbing and show ... -
At the Interface of Simulation and Experiment in Composite Cathodes for All-Solid-State Batteries
Bielefeld, Anja (2022-02)In the course of the exit from nuclear and fossil-fuel energy and the transformation of the mobility sector, batteries gain in importance. With their potentially high energy density, and high range for battery electric ... -
Chemie und Licht : Eine weihnachtliche Experimentalvorlesung
Albert, Barbara; Janek, Jürgen (2001)Dass viele chemische Reaktionen unter Lichterscheinung verlaufen, ist jedem geläufig. Chemische Reaktionen, bei denen es leuchtet, stehen mit einer groß,en Bandbreite für Demonstrationsversuche zur Verfügung: Wollen wir ... -
Chemische Triebkräfte : Von der Verbrennung zum Herzschlag
Janek, Jürgen; Seibert, Albert; Hofmann, Jan P.; Schwertfeger, Hartmut (2004)Was hat eine einfache chemische Verbrennung mit dem Herzschlag zu tun? Diese Frage soll im Rahmen einer physikalisch-chemischen Experimentalvorlesung beantwortet werden. Dabei fügen sich anscheinend weit voneinander entfernte ... -
Coating Techniques and Characterization of Protective Coatings for Electrode Materials in Lithium Ion Batteries -With the Examples of TiO2 on NCM by ALD and Plasma Polymerization of 1.4bis(trifluoromethyl)benzene on Lithium-
Moryson, Yannik (2023)Today's lithium ion batteries (LIB) are approaching their theoretical limit of 250 Wh/kg. In order to meet the increasing demands for batteries due to the energy transition and the associated electrification of passenger ... -
Controlled electrochemical growth of silver microwires
Rohnke, Marcus; Best, Timo; Janek, Jürgen (2005)The cathodic deposition of silver whiskers as microwires in the electrochemical cell Ag/AgBr/Ag has been investigated. From growth experiments observed with an optical microscope, we conclude that the growth process occurs ... -
