    报告简介

    Rechargeable batteries require reversible chemical reactions. In particular for high energy batteries, often the poor reversibility of the electrochemical reactions at the electrodes limit their applicability. Therefore, materials with reversible structural and morphological changes are essential. Electrodes contain nanoscale materials with light elements and are sensitive to humidity which makes their investigation challenging. Our research is concerned with the investigation of electrode materials with respect to structure, mechanics and morphology. Over the last few years we have developed and applied a set of operando characterization techniques that help in assessing electrode materials. We mainly use X-ray diffraction to determine the crystal structure of electrodes, light and electron microscopy for recording their morphology and the substrate curvature technique for measuring mechanical loads caused by changes in volume during electrochemical cycling. These techniques can be used on most insertion and conversion materials (e.g. materials for lithium and sodium batteries). Our test cells exhibit a very high reliability/reliability and our light microscopy inside a cell is at the physical resolution limit. As an example, we will present our recent data obtained on LiNi0.8Mn0.1Co0.1O2 that demonstrates how the different techniques can be combined to explore the reaction pathways and degradation mechanisms in this material. Our task within KIT is to investigate electrode materials with respect to reaction and degradation pathways. With this knowledge we attempt to optimize the battery materials in collaboration with synthesis and processing groups. This collaborative approach results in optimized/tailored materials and therefore is very promising for the development of novel batteries.
