The combustion and explosion of the vent gas from battery failure cause catastrophe for electrochemical energy storage systems. Fire extinguishing and explosion proof countermeasures therefore require rational dispose of the flammable and explosive vent gas emitted from battery thermal runaway.
Explosion hazards can develop when gases evolved during lithium-ion battery energy system thermal runaways accumulate within the confined space of an energy storage system installation. Tests were conducted at the cell, module, unit, and installation scale to characterize these hazards.
