(salary level TV-L E 13, 67%)
as soon as possible. We are offering three part-time positions (67%), fixed-term for 3 years.

Your tasks:

These positions are tied to working towards a doctorate.

The International Graduate School "BACCARA" offers a modern, comprehensive and interdisciplinary training program that enables its doctoral students to successfully carry out their research work while fostering personal development and, thus, preparing them for future successful careers in industry, administration/politics and academia.

-
Theory and Modelling
Theoretical work is conducted on very different length
- and time-scales: ab initio methods for the description of reaction processes, for the determination of electrochemical stabilities and the optimization of force fields; molecular dynamics simulations for improved understanding of structural and kinetic processes in electrolytes in particular also close to interfaces; machine learning concepts for improved analysis of experimental and simulated data.
-
Material Synthesis

Within this research focus, new molecules and solid materials are to be synthesized in a targeted manner in order to positively influence key performance parameters such as internal resistance, temperature windows, battery life and intrinsic cell safety.

The development of improved and sustainable synthesis pathways is also an important element.

Furthermore, surface chemistry and physical properties play a decisive role in the establishment and optimization of new cell chemistries and battery cell production e.g.

increased adhesion between the active material and current collector foil, or better binding of binder molecules to the surface of the active material particles.

-
Catalysis
In the field of lithium-ion batteries, catalysed reactions are of particular interest. The time
- and cost-intensive formation step after assembly and during the first charge is essentially based on a polymerization reaction of electrolyte constituents and lasts from several hours to days. Polymer-based solid-state batteries (SSBs) represent a broad field of research for catalysis research. Catalytic reactions for improved and sustainable synthesis of polymer electrolytes are to be researched and optimized within the framework of the research school. In addition, the understanding of catalytic decomposition processes can lead to an increase in the service life of materials and products, as well as a reduction in risks.
-
Analysis and Characterization
Individual molecular and solid materials, as well as the complex system "battery cell", require a broad portfolio of methods and proven experts for local and global material analysis in order to characterize different interfaces and interphases and investigate the micro
- and nanostructures of pure substances and composites. Reaction mechanisms and complex interactions in the overall context of electrochemical systems have to be elucidated and, as a result, targeted modifications have to be made so as to improve stability and performance and continue to meet ever-increasing requirements. In addition, analytical investigations provide valuable information and details of dynamic processes, ion mobility and structure-property-performance relationships. Finally, model materials, e.g. pure materials, single crystals, or thin film electrodes allow mechanistic investigations that are difficult to perform with complex materials and electrodes.

Recycling, Sustainability and Life Cycle Analysis

The successful and sustainable recycling of a battery cell begins with the design of the materials and the manufacture of the components.

According to the so-called "Design for Recycling" practice, innovative materials and processes are researched that enable the use of materials and, in the best-case scenario, individual components (e.g. electrodes) with mínimal performance losses.

Life cycle analyses can also be used to develop processes that enable the most energy-efficient separation and recovery of the individual cell materials, either as components or as raw materials.

In addition, the findings a
