Summary
• Cells without adequate vents can explode.• Heat release, propagation and flammability
vary among different chemistries of Lithium-Ion cells.
• Vented gasses can accumulate and cause an explosion.
• Composition of vented gasses contain H2, Hydrocarbons, CO, CO2 and concentrations vary with SOC.
