However, due to the thermal instability of lithium batteries, the probability of fire and explosion under extreme conditions is high. This paper reviews the causes of fire and explosion of lithium-ion batteries from the perspective of physical and chemical mechanism. Conferences > 2018 2nd IEEE Conference on E...
Some of these batteries have experienced troubling fires and explosions. There have been two types of explosions; flammable gas explosions due to gases generated in battery thermal runaways, and electrical arc explosions leading to structural failure of battery electrical enclosures.
In real scenarios, explosions are often caused by internal high temperatures or electric sparks generated by battery electrodes. To make the study more generalizable, the ignition location was designated as the center of the upper surface of the battery module ( x axis: 2.375 m, y axis: 0.5 m, z axis: 1.2 m).
Conclusions Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules.
The energy storage system was installed and put into operation in 2018, with a photovoltaic power generation capacity of 3.4MW and a storage capacity of 10MWh. The explosion destroyed 0.5MW of energy storage batteries. It is understood that the lithium-ion battery cell supplier of the energy storage station is LG New Energy.
During a battery TR event, the flammable and explosive gases (FEGs) vented by the battery are prone to accumulating and result in explosions . Additionally, the shock waves produced when a sealed box explodes are more difficult to dissipate, further damaging the batteries in normal conditions.
