Contract time limit:
IEK-9 Energy Materials group is currently looking for a Master thesis candidate for the earliest possible employment date for a thesis in the area of electrode materials for metal-air batteries.
Metal-air batteries are a possible alternative to lithium-ion batteries that is being intensively investigated. Applications range from mobile to stationary/grid-scale. One of the most important factors to ensure re-chargeability of the batteries is the performance of the cathode, were oxygen reduction and evolution take place.
Our group focusses on fibre-based carbon electrodes from electrospun polymer fibres. They are a novel approach for the development of gas diffusion electrodes for metal-air batteries. They feature a lot of positive properties that make them a possible replacement for state-of-the-art electrodes. Currently, we are working on the implementation and testing of catalyst materials.
Your Tasks:Preparation and Characterisation of electrodes using electrospinningAnalysis of electrodes using microscopic methods (SEM) as well as spectroscopic methods (Raman)Development of a procedure to implement catalyst materials and subsequent electrochemical investigation (potentiodynamic polarisation, galvano- und potentiostatic measurements)
Your Profile:Master’s student in Chemistry (focus on materials and/or heterogenic catalysis), Materials Science or related fieldsExtended experience working in a chemical lab as well as first experience with electrochemisty and electrochemical analysis methods is helpful. Adequate computer skills (Origin, Matlab) and English proficiency are expected
