Abstract (englisch):

With increasing energy density safety and thermal management of Li-ion batteries is becoming more and more important, because the thermal runaway can cause an ignition or even explosion with simultaneous release of toxic gases. In the last nine years we have established battery calorimetry as a versatile characterization technique, which allows advancements for the thermal management and the safety of batteries. With six adiabatic Accelerating Rate Calorimeters of different sizes and two sensitive Tian-Calvet calorimeters combined with cyclers we operate Europe’s largest battery calorimeter center, which enables the evaluation of thermodynamic, thermal and safety data on material, cell and pack level under quasiadiabatic and isoperibolic environments for both normal and abuse conditions (thermal, electrical, mechanical).
Calorimetry allows the collection of quantitative data required for optimum battery performance and safety. This information is applied to define the requirements for thermal management. It will be explained how the two different types of calorimeters can be used for studies on heat generation and dissipation of Li-ion cells. ... mehr
