Calorimetric studies and safety tests on lithion-ion cells and post-lithium cells Open Access Government interviews Dr Carlos Ziebert, of the Karlsruhe Institute of Technology (KIT), who explores the thermal and safety properties of batteries across calorimetric studies. The group batteries – calorimetry and safety – focus on calorimetric studies and safety tests on lithium-ion cells and post-lithium cells. Depending on the cell size and application, different types of calorimeters are used in Europe's largest Battery Calorimeter Laboratory, established in 2011. It provides seven Accelerating Rate Calorimeters (ARCs) from Thermal Hazard Technology allowing the evaluation of thermodynamic, thermal and safety data for Lithium-ion and post-Li cells on material, cell, and pack levels for both normal and abuse conditions (thermal, electrical, mechanical). The lab also includes glove boxes for cell assembly and disassembly, many temperature chambers, a thermal camera, and cyclers with several hundred channels. It contains extremely sensitive 3D Calvet calorimeters, providing thermodynamic parameters and gas chromatography-mass spectrometry systems from Perkin-Elmer for venting gas analysis.
