The ARC tests measured self-heating behavior and provided quantitative data on the onset of thermal runaway. The battery configuration included LiNi 0.8 Mn 0.1 Co 0.1 O 2 (NMC811) cathodes ...

Oxygen release from charged cathode materials triggers runaway around 220 °C. The study also demonstrated that battery design significantly affects TRF. Increasing the aspect ratio (height/diameter) ...
