Mikroskopie und Mechanische Messungen

Microscopy

A prime task of microscopy is to examine materials in a highly precise manner and to observe their modification by various factors in real time. Light microscopy is employed to examine materials inside the electrolyte in real time. It alone offers the possibility of observing processes in real time in realistic surroundings. The technique is used, for example, to study lithium deposition under conditions comparable to those in real cells.

The scanning electron microscope is a versatile tool for studying materials at a high resolution. For battery materials, the focus is on materials sensitive to air that can be transferred using a special transfer system.

Mechanical Measurements

Mechanical tension is formed in electrode materials during the storage and removal of lithium. Since this stress can lead to damage, measurement of the stress is helpful in assessing the reliability of material. An effective means to conduct such experiments is the substrate curvature method, in which a thin film is observed on a carrier, in this case the substrate. If the film undergoes mechanical tension, the electrode film–substrate system curves slightly. By measuring the substrate curvature, the tension in the electrode film can be calculated. At HIU it is uniquely possible to conduct such measurements on the basis of composite electrodes such as used in real batteries.
