Studying Electrochemical Reactions Using In Situ SAXS
Many of the obstacles and opportunities associated with next-generation electrochemical energy storage lie in the structural complexity of multiphase material systems. The lack of knowledge about suitable, structure-sensitive in situ techniques is impeding progress on such battery systems. In situ small-angle X-ray scattering (SAXS) and X-ray diffraction (XRD) hold the key to the monitoring of physicochemical mechanisms during, e. g., electrochemical cycling of battery materials. Understanding these processes at the nanometer/atomic level is a turning point in the development and performance improvement of next-generation battery systems.
Anton Paar has successfully manufactured instruments for small-angle X-ray scattering for more than 60 years. With the latest model – the SAXSpoint 5.0 system – a dedicated battery cell is available for in-situ combined electrochemical and SAXS measurements in the home laboratory. Anton Paar also recently released the new state-of-the-art X-ray diffractometer, XRDynamic 500.

Heiner Santner (PhD) has completed a PhD in technical chemistry from Graz University of Technology and held a postdoctoral position at ICMAB - Barcelona with a research focus on synthesis and characterization of energy storage devices by X-ray scattering methods. Since 2006 he is a product specialist for small- and wide-angle X-ray scattering instrumentation at Anton Paar and has developed a deep expertise in SAXS/WAXS/GISAXS instrumentation and its application to the analysis of nano-structured materials like colloidal systems and thin films.
