The thermal runaway of lithium batteries is an outstanding example for an extreme event
in a complex technical system. Thermal runaway refers to the ignition or explosion of a
battery as consequence of a self-accelerating heating process that is initiated by
stochastically occurring internal or external triggers. The corresponding safety problems
are today a major factor impeding the introduction of lithium batteries for electromobility
or storage of energy from sustainable sources. The objective of the present study is to
understand, predict and control thermal runaway in lithium batteries. A combined
methodology of multi-scale deterministic modeling, stochastic simulation, and
experimental analyses is proposed. This will allow probabilistic predictions of thermal
runaway events and, particularly, the design of an early-alert and risk-aware heat
management system for lithium batteries.
