Characterization of penetration induced thermal runaway propagation process within a large format lithium ion battery module (2015, methodology): “For example, small impurities mixed in the electrode active materials, which cannot be eliminated during the manufacture of batteries [6], may lead to short circuit defects after a long time of incubation [21] and therefore cause TR at some unpredictable point of time.”

A Review of Lithium-Ion Battery Fire Suppression (2020, background): “• Mechanical abuse (penetration, pinch, and bend) [93,110]: Mechanical abuse, usually caused by external mishap to the LiB such as car crash or during installation, can result in electrical shorting between the electrodes, via the electrolyte, producing localised heating.”
Thermal behaviour analysis of lithium-ion battery at elevated temperature using deconvolution method (2014, background): “Thermal and electrical abuses in the battery reactions occur at a high temperature under conditions of heating, crushing, or short-circuit [7–10].”
