Mechanistic calendar aging models provide physically interpretable insights into battery degradation but require extensive experimental effort and often suffer from poor parameter identifiability. This work combines model reduction with optimal experimental design (OED) to enable efficient and robust parametrization. A structured workflow is applied, including identifiability analysis, targeted model reduction, initial parameter estimation, OED-based experiment […]

The EU Battery Regulation (EU) mandates a digital battery passport for traction, light‑mobility, and industrial batteries above 2 kWh from February 2027 onward, regardless of cell chemistry. As a result, lead‑acid batteries—widely deployed in industrial vehicles, backup systems, and motive‑power applications—must fulfill the same transparency and lifecycle documentation requirements as lithium-based batteries. Given their strong cost […]

Knowledge of the open-circuit voltage (OCV) behaviour of cells and batteries is important for ageing diagnosis as it enables separation of degradation modes such as loss of lithium inventory (LLI) and loss of active material (LAM). While lab tests usually enable reliable extraction of OCV information, the same analysis methods often fail on field data […]

The digital battery passport, mandated by the new EU Battery Regulation, will be required from February 2027 for the majority of large batteries placed on the EU market. It comprises 78 static and 19 dynamic attributes designed to characterize and trace the entire battery life cycle—from raw material extraction and manufacturing to usage and recycling. […]

Electromobility and the storage of regeneratively generated electrical energy place significant demands on the performance and costs of lithium-ion cells. Achieving these goals necessitates a deep understanding of the material properties of raw materials and manufacturing processes for electrodes. Product development and production require precise measurement and control of numerous parameters to tailor cell properties […]

The study focuses on developing novel boron-based high-entropy materials for use in supercapacitors and energy storage devices. The structural, morphological, phase, and chemical properties, will be analyzed using XRD, SEM, TEM, EDX methods. The electrochemical performance of the high-entropy boride (HEB) particles as electrode materials will be evaluated in symmetric device configurations.

As Europe accelerates the transition toward battery-based energy and mobility systems, securing access to critical raw materials (CRMs) becomes increasingly important. In addition to primary extraction, end-of-life products represent a largely untapped resource base for secondary raw materials. This study investigates the urban mining potential of CRMs, focusing on cobalt as a representative example, to […]

For applications that require both high energy densities and a long cycle life with high safety standards from their batteries, lithium-ion batteries (LIBs) containing liquid electrolytes are still the cell chemistry of choice. The capacity limiting component in common LIBs is the lithium metal oxide cathode. The most prominent cathode material used for high energy […]

In the last years, there were a lot of new research articles and findings that question state-of-the-art accelerated aging tests and their meaning for the assessment of aging and the accuracy of lifetime prediction. Standard accelerated aging tests increase stress factors such as C-rate and reduce idle periods to zero compared to the dedicated long-life […]

Thermal runaway in lithium-ion batteries is a significant safety concern, particularly in large-scale energy storage systems. In such scenarios, the release of combustible gases and ejected particles can lead to fire propagation. Although these phenomena have been studied extensively, the interaction between electric arcing resulting from the opening and closing of switches or contacts through […]
