Full‐Dimensional Analysis of Gaseous Products to Unlocking In Depth Thermal Runaway Mechanism of Li‐Ion Batteries

evolution during heating process and the unreacted flammable/toxic organic species would exit in the form of high temperature/high-pressure (HT/HP) vapors within batteries, indicating higher potential safety risks. Additionally, the in depth understanding of the TR mechanism outlined above provides a clear direction for the design/modification of thermostable electrodes and non-flammable electrolytes for safer batteries.
