New testing capabilities in the fire lab, the Acceleratory Rate Calorimetry (ARC) Apparatus

Sep 13, 2024

The FRISSBE Department at ZAG has just welcomed a new apparatus in the fire laboratory, the Acceleratory Rate Calorimetry (ARC EVx) from Thermal Hazard Technology. We acquired the ARC in consortium with the L18 Laboratory for Modern Battery Systems from National Institute of Chemistry, and we want to express our gratitude to ARIS (Slovenian Research and Innovation Agency) for partially financing the ARC EVx's acquisition. The ARC EVx brings new opportunities to carry out our research on the safety and performance of battery cells. We can now perform thermal degradation studies under various conditions (adiabatic, ramping, isothermal, isoperibolic and step isothermal heating modes) to determine the onset of thermal runaway and the energy released during the phenomenon. It also allows us to conduct abuse testing (short circuit, overcharge and nail penetration), performance testing (heat capacity, charge/discharge cycling) and gas collection. The latter is especially relevant as it allows, combined with other methods (GC-MS or FTIR), the characterisation and quantification of exhaust fumes emerging during thermal runaway. For any enquiries on potential collaboration or research ideas, please get in touch with Dr Ulises Rojas from FRISSBE or Sara Drvarič Talian from KI.
