We induced thermal runaway in a single LiPo pouch cell (which are combined to make a lithium ion battery) by electrically "backdriving" it until it overheated and eventually caught fire. We measured the gas and particle emissions using Cambustion fast response analysers (FID50 for Hydrocarbons, NDIR50 for CO and CO2, DMS500 for nanoparticles, including the real-time size distribution from 5 - 1000 nm), as well as instrumenting the cell for temperature. Here are the results.
