Calorimeters to advance thermal management and battery safety

The development of safe lithium-ion cells is of utmost importance for a breakthrough in the electrification of transport and for stationary storage, because an...

The Battery Safety Center at the Karlsruhe Institute of Technology’s (KIT) Institute for Applied Materials operates Europe’s largest battery calorimeter laboratory.

KIT’s facility allows for the evaluation of thermodynamic, thermal and safety data for lithium-ion cells on material, cell and pack level under adiabatic and isoperibolic environments for both normal and abuse conditions (thermal, electrical, mechanical).

Battery Calorimeters for Battery Safety

Battery calorimetry is an important method for the effective monitoring of thermal runaway in batteries and is used to help improve the effective level of safety in batteries.

Thermal runaway in batteries can lead them to an uncontrollable increase in temperature, which in turn can cause an ignition, or even explosion, of the battery with simultaneous release of toxic gases.

Using Battery Calorimeters to Monitor Heat Data

Sophisticated battery calorimetry and thermography can be used to monitor and collect heat data which can then be used to identify quantitative correlations between different critical safety and thermally related parameters within battery cells.

The temperature, heat and internal pressure evolution can be studied, while operating cells under conditions of normal use, abuse or accidents.
