4. Conclusions The tests show that lithium-ion battery cells exposed to fire are significantly more reactive at 100% SOC than at lower SOC values and energetic outbursts were observed. The HRR peak values thus varied in a rather wide range, between 13 and 57 kW for batteries with approximately 100 Wh energy capacity.
New energy vehicles with lithium-ion batteries are rapidly developing, shuttling on the urban underground highway. Lithium-ion batteries themselves have a high risk of fire. Under the effect of external thermal sources, external compression, puncture, and short circuits, etc., an uncontrollable chain chemical reaction will occur inside the battery.
The main reason for lithium-ion battery fires was thermal runaway. If it was not controlled, thermal runaway may cause the battery to rupture and release toxic and highly flammable gases. If these flammable gases are ignited, they might cause a fire or explosion (Yuan et al., 2020).
Multiple requests from the same IP address are counted as one view. Lithium-ion batteries (LIB) pose a safety risk due to their high specific energy density and toxic ingredients. Fire caused by LIB thermal runaway (TR) can be catastrophic within enclosed spaces where emission ventilation or occupant evacuation is challenging or impossible.
