Laminar burning velocity of gases vented from failed Li-ion batteries

In the last decade, several fires and explosions caused by Li-ion batteries (LIBs) have been reported. This can be attributed to thermal runaway catastrophic failures of LIBs that release combustible gases, which when mixed with air lead fires. To address this explosion hazard, we determine laminar burning velocity (LBV) three gas compositions associated failure a pseudo (simplified) in 20-L sphere at 300 K 100 kPa. simplified avoids toxic gases experiments represent desired characteristics. The LBVs case range from approximately 1050 mm s −1 . Additionally, four different reaction models are used estimate these compositions. We compare theoretical experimental results prediction accuracy models.
