  3. 5 Stacked E-Tablets

  4. Li-Ion Combustion Chamber Test Maximum Pressure: 28 PSI

  5. Paper from SAE International Components of vented gas Pressure rise of LiCoO2 cells at 100% SOC Kg: Explosion Index (Proportional to Rate of Pressure Rise) Quantification of Combustion Hazards of Thermal Runaway Failures in Lithium-Ion Batteries Somandepalli et al / SAE Int. J. Alt. Power. / Volume 3, Issue 1 (May 2014) Paper number: 2014-01-1857

  6. 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.
