• Onset of exothermic reactions is determined by the anode side  Deposition of metallic lithium on the anode surface should be prevented  Effective and thermally stable SEI is key for a safe LIB • High reactivity of the cathode in presence of electrolyte dominates the kinetics during thermal runaway  Layered and spinel-type electrodes exhibit a decreased thermal stability in the charged state  The presence of nickel largely reduces the thermal stability of positive active materials (especially in the charged state; Ni4+) independent of the structure (layered/spinel)  An increasing nickel content in the NCM structure intrinsically reduces the thermal stability  Overall, aging effects have a larger influence on the thermal stability of layered transition metal oxides like NCM compared to spinel-type or olivine-type active materials

• Failures initiated by mechanical insult to cell 1 which is connected to cell 2 through constantan bridge wire • Development of a testing fixture to increase reproducibility • Additional effort to maintain electrical connection with cell 1 after runaway event • Use of spring on nail to apply opposing force keeping cell from ejecting after runaway (images below)
