Modelling and data analysis of electrochemical systems, focusing on microstructures in solid-state batteries
Addressing, isolating and understanding electrochemical phenomena by experiments can be quite challenging in many cases. The research group Bielefeld switches perspectives and translates these phenomena into mathematical and/or geometrical models of reduced complexity. Experimental motivation, input and support are essential ingredients for our work at the interface of simulation and experiment.
(All-)solid-state batteries are in the spotlight of our work and we are particularly interested in microstructure effects and their influence on the battery cell properties. The goal is to develop (electrode) design guidelines and identify preferred cycling conditions by electro-chemo-mechanical experiments and simulations that complement one another. Therefore, apart from grain boundary effects or electrode characteristics such as composition and particle distributions, the shapes, sizes and morphologies of particles and pores are of interest for us.
