Composition and Explosibility of Gas Emissions from Lithium-Ion Batteries Undergoing Thermal Runaway

Lithium-based batteries have the potential to undergo thermal runaway (TR), during which mixtures of gases are released. The purpose this study was assess explosibility gaseous emission from LIBs an NMC-based cathode runaway. In current project, a series pouch lithium-based battery cells exposed abuse conditions (thermal) total amount released and composition gas mixture. First, were placed in closed vessel, pressure temperature rise inside vessel measured. second step, analysed using Fourier transform Infrared (FTIR) spectrometer. We found that up 102 ± 4 L, with clear dependence on capacity. This showed concentration emissions such as carbon monoxide (CO), methane (CH4), ethylene (C2H4), ethane (C2H6), hydrogen cyanide (HCN) increased higher cell Of five studied flammable gases, maximum concentrations (16.85 vol%), (7.6 (7.86 vol%) identified be within their explosible range. Applying Le Chatelier’s law, calculated lower explosion limit (LEL) 7% volume fraction obtained for upper (UEL) mixture also 31% volume. A filter comprising pyrobubbles used removal components abuse. investigation revealed highly effect HCN (up 94% removal) CO2 100% removal). Herein, we report dependency method trigger measured temperature.
