X-ray Diffraction Platform
CIC energiGUNE's X-ray diffraction platform offers a comprehensive service of X-ray diffraction and small angle scattering for the structural, micro-structural and morphological study of materials. It includes two powder diffractometers and a small angle scattering apparatus, together with temperature chambers, robot sample changers and an in-situ electrochemical cell of our own design. Structural analysis of materials can then be performed varying parameters such as atmosphere, temperature and oxidation state. The platform offers service of measurements as well as analysis of the results and is open to internal as well as external users.

SERVICES OFFERED BY THE ASSET
Measurement of phase and structural changes taking place in electrode materials during battery operation
Coupling our in-situ electrochemical cell with one of our X-ray diffraction equipments (D8 Advance, D8 Discover) or Small Angle X-ray Scattering (SAXS Nanostar) we can study changes in the morphology and crystalline structure of a material during its electrochemical reaction. This is typically used for electroactive electrode materials for secondary batteries but can also be used for the study of primary batteries as well as any electrochemical reaction.
Measurement of the microstructure (porosity, size of nanoparticles, order in disordered materials ...) at low angles
This service is based on the use of the Small Angle X-ray Scattering technique (SAXS) which allows the study of the morphology (particle size, internal or external porosity etc…) and the nanometer and subnanometer range. 2D mapping of the samples is also possible, with a micrometer resolution, in order to observe density changes and compare the SAXS measurements at various positions of a sample. SAXS requires powder sample or flat sample (typical thickness 50um-2mm depending on absorption).
