Devices for energy storage play an importance role in our daily life. Solid state Lithium-Ion-Batteries present an attractive solution with a lot of potential for further development. The goal is to develop safe and environmentally friendly batteries with improved electrochemical properties while at the same time decrease the volume and weight of the devices. To realize this it is fundamental to gain a better understanding of the correlation between microstructure and local Li-Ion movement. One of the obstacles is to analyze the relevant processes on a sufficiently small scale. Electrochemichal Strain Microscopy (ESM) is a relatively new technique based on Atomic Force Microscopy (AFM). It allows a high resolution analysis of the ion conductivity with regards to the microstructure of the material. To understand how local ion migration translates into global ion conductivity ESM is used correlatively with other microscopy techniques such as Scanning Electron Microscopy (SEM). The gathered insights will aid the development and synthesis of improved Energy materials for the future.

Nino studied material science at RWTH Aachen University. During his Master studies he specialized in the fields of surface technology and construction engineering materials. In his Master thesis, for which he worked at the DECHEMA in Frankfurt am Main, he characterized the corrosion properties of titanium alloys. At the Forschungszentrum Jülich he will obtain new insights on the topography, degradation mechanisms and electrical and ionic conductivities of energy materials. To achieve this he is utilizing „electrochemical strain microscopy“. Nino likes to spend his free time outside, ideally at the river fly fishing.
