In this thesis, experimental and computational methods are developed and combined on electrode and cell level in order to allow for a thorough evaluation of high performance and safety characteristics of lithium-ion batteries, focusing on a characterization of cell thermal runaway. Means of studying the evolution, initiation, and possible mitigation of cell thermal runaway are presented. Due to the thermal nature of this problem, the focus is laid on the investigation of heat generation and heat dissipation at elevated temperatures and currents.
