Manufacturer of industry batteries are obliged to take back used batteries and initiate the classification process for reuse or recycling. In order to realize this, within the framework of the publicly funded project ReCycle, three diagnostic stages have been defined and evaluated. The initial stage takes place in the field during usage, where the current […]

Electrochemical Impedance Spectroscopy (EIS) is a powerful tool for characterizing Lithium-Ion batteries (LIB). However, it relies on strict adherence to Linear Time-Invariant (LTI) conditions for valid interpretation. A violation of the LTI criteria can significantly impact the reproducibility and accuracy of impedance spectra. One influential yet often overlooked factor is a superimposed DC current. Many […]

Now a days, solid-state lithium-metal batteries are attracting interest as potential replacement for conventional Li-ion batteries Replacing the organic liquid-based electrolyte with a lithium-ion conducting solid-state electrolyte (SSE) reduces safety issues, release of toxic gases, risk of thermal runaway and short-circuiting. Among the different types of oxide-based inorganic solid-state electrolyte, the NASICON-structure, lithium aluminium titanium […]

The conflict between high charging rates and battery lifetime is still a challenge in the development of electric vehicles and power-tools. It is necessary to identify operating conditions that trigger degradation processes to be able to combine fast charging with a long battery lifetime. Therefore, non-invasive diagnostic methods to monitor real-time dynamics within the battery […]

Employing lower temperatures can render lithium batteries inert, halting almost all chemical reactions within the cells. Our in-house developed high-precision nail penetration setup has already provided valuable insights how critically damaged lithium battery cells behave at low temperatures. In the present study, tests were performed on three different cell types with varied cathode types and […]
