SoTeXS (Soft-to-Tender X-Ray Spectroscopy) is supposed to extend and complete the HZB portfolio for battery research, where currently 12 beamlines contribute with 10 different methods. Both energy storage and the required sustainability in mobility and transport demand novel battery concepts. The use of abundant, environment friendly materials, detailed insights into operating electrochemical cells, and understanding of degradation processes will lead to new, sustainable and more efficient materials for energy storage (in line with the battery 2030+ roadmap “Sustainable batteries of the future”). In particular, a combination of the soft and tender X-ray regime (here: 0.5 – 5keV) is an excellent way to investigate almost all elements relevant for battery applications and their “behaviour” in batteries at work. Uniqueness: SoTeXS will be designed for metrological investigations together with the PTB, making it highly attractive for industrial research. It completes the battery portfolio, which is about to be consolidated into a battery hub together with PTB and BAM, to facilitate IR spectroscopy, X-ray emission and absorption (UPS, XPS, HAXPES, NEXAFS, EXAFS), Resonant Inelastic Scattering (RIXS), small and wide angle scattering (SAXS, ASAXS, WAXS), imaging and tomography. Partners: HZB, PTB
