Gas Emissions at Fire, Overheating, and Overcharging Events for Lithium-Ion Batteries
The webinar, hosted by Underwriters Laboratories on September 30, 2020, was presented by Professor Bengt-Erik Mellander, Ph.D., from Chalmers University of Technology, and Fredrik Larsson, Ph.D., from Alelion Energy Systems AB.
The presenters' extensive academic knowledge, field experience and industrial involvement of abuse testing and measurements of flammable and/or toxic gas emissions detailed the risk for fire, explosion and toxicity from Li-ion batteries subjected to off-nominal conditions. Qualitative and quantitative gas component analysis including the detection of the elusive HF (hydrogen fluoride) in the event of external fire, overheating or overcharging of Li-ion batteries were addressed for commercial cells with different chemistries.
