The Center for Materials Research (Dr. Matthias Elm) is inviting applications for two
(salary scale TV-H 13, 50 %)
The positions are available from now on for three and a half years. The project entitled NIKO – Nanostructured ion-conducting composites as key technology for efficient energy storage and converter technologies is part of the NanoMatFutur junior research group at the Center for Materials Research funded by the BMBF. The position is provided for a promotion within the framework of the Graduate Program in Materials Research - Prima.
In the framework of the project „NiKo“ a junior research group is built up at the Center of Materials Research, which focusses on the development of new lithium ion- and oxygen ion conducting composites for optimized electrode materials for lithium-ion-batteries and low temperature oxygen permeation membranes, respectively. Within the project the influence of the microstructure on the electrochemical properties (electronic and ionic transport) is investigated and systematically manipulated to develop competitive composites for applications. The Center for Materials research offers access to a variety of state-of-the art characterization methods. With the results obtained, the economic potential of the composites will be evaluated in close cooperation with partners from industry.
The composites based on lithium-ion-conductors (Position A) are prepared from micro- and mesoporous starting material by plating. Their structural properties will be characterized by e.g. SEM, XRD. The influence of metal plating on the Lithium-storage will be investigated by electrochemical methods, such as impedance spectroscopy, cyclic voltammetry or GITT. The results obtained will be used to prepare electrode materials with optimized properties for lithium-ion batteries.
Composites based on oxygen ion conductors (Position B) will also be prepared from micro- and mesoporous starting material by plating. The characterization of the transport properties of oxygen will be investigated using impedance spectroscopy and tracer diffusion experiments. Additionally, measurements of the oxygen permeation will be performed on promising composites to identify the ideal microstructure for novel oxygen membranes.
The results obtained will be presented to the international research community on national and international conferences as well as in form of publications.
Last but not least you will have the possibility to contribute to highly topical research in the field of modern energy storage and converter technologies (high temperature oxygen permeation membranes and lithium-ion solid state batteries).
You have successfully finished your university degree in chemistry, physics, material science or a related field and you have a strong interest in the field of physical solid state chemistry. Experiences in the field of electrochemistry or the characterization of materials properties with physical or chemical methods (e.g. conductivity measurements, diffraction, electron microscopy) are welcome. In the project a close collaboration with partners from industry is necessary. Thus, you should have good command of English. We are looking for highly committed and motivated persons who enjoy socializing within a modern material science research team but who are also capable to develop an independent research profile.
The Justus Liebig University, Giessen seeks to support women in scientific research. Therefore we strongly encourage women to apply for the available position. As a family friendly institution of higher education, the Justus-Liebig-University of Giessen welcomes applicants with children.
Please send your application (no e-mail) stating the application number 485/08444/Z with the usual documents until September, 07th, 2017 to Dr. Matthias Elm, Zentrum für Materialforschung, Heinrich-Buff-Ring 16, 35392 Giessen. Applicants with disabilities but otherwise equal qualifications will be preferred. Please do not send originals documents as these will not be returned after end of the selection procedure.
