The structural and imaging analysis infrastructure provides advanced imaging of energy materials by 3-dimensional reconstruction by using Focussed Ion Beam (FIB) and tomography and operando structural and chemical characterizations of materials and interfaces. These services can identify structural but also chemical changes of materials and components in a complementary approach, which is based on world class equipment and experienced researchers in the field of energy storage materials and components. The services are linked to the imaging center at DTU, which also has close connections to MaxIV and ESS, and also provides 4D imaging of materials (3 D in space and 4th dimension in time), as well as operando characterization of materials “at work”. The infrastructure is composed of:

• 3D imaging (FIB Cross Beam, Computer Tomography)

• In-situ/operando XRD (using capillary cells)

• In situ/operando Raman

• High resolution microscopy

• XPS

The current services offered by the Imaging & structural analysis infrastructure are:

• 3D reconstruction of energy materials after different use periods, especially porous electrode materials for batteries and electrolysis cells.

• In situ and operando Surface Raman spectroscopy on Lithium ion conductors and solid oxide cell electrodes

• Operando X-ray diffraction to investigate structure – state of charge relationships in battery materials.

• In-situ transmission electron spectroscopy is under development

These advanced services can be complimented by state-of-the-art electron microscopy and X-ray diffraction if desired.
