TY - CONF A1 - Holtappels, Kai T1 - Trust in Hydrogen Technologies - Safety Issues in the Hydrogen Value Chain N2 - In June 2020, updated in July 2023, the German government presented the National Hydrogen Strategy (NHS), its first strategy for achieving the goals of its hydrogen policy. The NHS sets out a coherent framework for action for the future production, transportation and use of hydrogen and its derivatives, including the corresponding research, innovations and investments. Various measures have been defined to achieve goals such as the decarbonization of various sectors and the market introduction of hydrogen technologies. This will ultimately lead to the introduction of many “new” technologies in many areas of our daily lives, which will only be successful if decision-makers and the public are convinced that these technologies are safe. Therefore, the safety of hydrogen technologies is an important pillar in gaining and maintaining confidence in these new technologies. Safety must keep pace with, or better still anticipate, trends in technological development in order to avoid overly conservative and expensive s T2 - 10th World Energy Congress (WEC 2024) CY - Singapore DA - 12.11.2024 KW - Hydrogen Safety KW - Trustworthiness KW - Safety research KW - Accidents PY - 2024 AN - OPUS4-62174 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER - TY - CONF A1 - Böttcher, Nils T1 - Nominal and Off-Nominal Battery / High Energy Storage Testing Off-Nominal cell and battery testing at BAM N2 - The abuse testing of electrochemical energy storage systems poses a major safety challenge.

Furthermore, aging experiments were conducted for 7 days under static conditions in 100 MPa hydrogen and the physical and mechanical properties of the rubber materials were examined before and after hydrogen exposure. Fretting tests revealed that the wear of these compounds is significantly affected by the hydrogen environment compared to air, especially with NBR grades. After aging experiment, the friction response of HNBR grades is characterized by increased adhesion due to elastic deformation, leading to partial slip. T2 - 4th Int.

Done right, automation can deliver reliable quantities of excruciatingly detailed data, produced in a reproducible and traceable way. This data then needs sorting and organising, and a good structure of metadata is a good start to long-lasting data. This metadata collection is an essential part of our “holistic experimentation”-approach. In this approach, we try to ensure that all aspects of the experimental chain are performed to a high standard, so that experimental integrity is maintained. In other words: as a failure in one of the components of the chain can make an entire experiment worthless, we must ensure each component is done (and documented) well. In this talk, we show how we 1) synthesise well-documented sample series, 2) apply a complete end-to-end X-ray scattering characterisation methodology to those samples, and 3) can link the data from the synthesis to the structural details obtained from the scattering experiments in a visual dashboard. Furthermore, we will show examples on how data can be organised in hierarchical structures in HDF5-based datafiles, and how this helps move towards more trustworthy, traceable science. About the speaker: Brian Pauw is a full-stack X-ray scattering expert with over 15 years of experience in materials science. After earning a Ph.D. in Chemical Engineering from the Technical University of Denmark in 2009, Brian advanced scattering techniques at Japan’s National Institute for Materials Science before joining BAM (Federal Institute for Materials Research and Testing) in Germany as a permanent researcher. At BAM, Brian focuses on small-angle scattering of polymers, metals, catalysts, and more – developing precise methodologies for data collection, correction, and analysis. They also lead efforts in laboratory automation, including robotic systems for reproducible sample preparation, aiming to enhance the efficiency and reliability of experimental workflows.

N2 - Since their introduction, Lithium-ion batteries (LIBs) have revolutionized the world of portable electronics and sustainable mobility[1]. LIBs currently play a pivotal role across several sectors, thanks to their long cycle life, fast-charging capabilities, unmatched energy densities, and a broad operating temperature range. Given the increasing demand of this technology[2,3], challenges including safety concerns, limited resource availability, and environmental impact need to be addressed. To improve the next-generation systems, understanding the cell degradation pathways is crucial. However, the complexity of these systems, comprising organic and inorganic compounds in various aggregation states, poses challenges to studying the involved degradation processes. Inspired by geochemical studies, which displayed lithium isotope fractionation in dynamic natural systems, attributed to the high mass difference (ca. 16%) between the heavier (ca. 7Li, 92.5%) and the lighter isotope (ca. 6Li, 7.5%)[4], this work investigates weather a difference in Li isotope distribution within battery components can serve as a diagnostic and/or predictive tool for determining the remaining useful lifetime (RUL) of batteries[5]. Initial observations of Li isotope variation during battery aging were made in commercial cells. This was followed by systematic studies based on lab-scale coin-cells fabricated with different cathode materials[6]. While multicollector ICP-MS (MC-ICP-MS) investigation of each cell component enabled quantification of Li isotope fractionation in new and aged batteries with a 0.2 ‰ precision, glow discharge mass spectrometric (GD-MS) analysis provided spatially resolved information on Li isotopic distribution variation upon cells aging. The results display a meaningful correlation between post-mortem chemical analysis and electrochemical cells’ performance, highlighting the potential of Li isotope distribution in the electrodes as both a benchmark for battery degradation and a valuable indicator for assessing battery RUL.

Especially in conjunction with nano- and advanced materials which are generally recognized for their great potential in solving current material science challenges, such systems can make disrupting con-tributions. Consequently, new tools that enhance the development and optimization cycle of nano- and advanced materials are crucial. In this contribution, we present our Self-Driving Lab (SDL) for Nano and Advanced Materials [1], that integrates robotics for batched autonomous synthesis – from molecular precursors to fully purified nano-materials – with automated characterization and data analysis, for a complete and reli-able nanomaterial synthesis workflow. By automating the processing and characteriza-tion steps for seven different materials from five representative, completely different classes of nano- and advanced materials (metal, metal oxide, silica, metal organic framework, and core–shell particles) that follow different reaction mechanisms, we demonstrate the great versatility, reproducibility, and flexibility of the platform. The system also incorporates in-line characterization measurement of hydrodynamic diameter, zeta potential, and optical properties (absorbance, fluorescence). In general, the interface with data analysis algorithms from in-line, at-line, and off-line measure-ments is of great importance for closing the design-make-test-analyze cycle and using these platforms efficiently. Here, we will give examples of how automatic image seg-mentation of electron microscopy images with the help of AI [2] can be used for reduc-ing the “data analysis bottleneck” from an off-line measurement. We will also discuss various machine learning (ML) algorithms that are currently implemented in the backend and can be used for ML-guided, closed-loop material optimization in our SDL. Lastly, we will show our recent efforts [3] in making the workflow generation on SDLs more user-friendly by using large language models to generate executable workflows automatically from synthesis procedures given in natural language and user-friendly graphical user interfaces based on node editors that also allow for knowledge graph extraction from the workflows. In this context, we are currently also working on a com-mon description or ontology for representing the process steps and parameters of the workflows, which will greatly facilitate the semantic description and interoperability of workflows between different SDL hardware and software platforms. These features underscore the SDL’s potential as a transformative tool for advancing and accelerating the development of nano- and advanced materials, offering solutions for a sustainable and environmentally responsible future.
