The development of surface film on the cathode electrode is the main reason for the electrode failure. It reduces the reaction rate for both Li-ion intercalation and de-intercalation. Because of the surface film on the cathode, the structural phase transition from hexagonal to cubic or spline takes place. It is found that when the temperature increases from …
Overcharging. Charging a lithium-ion battery beyond its capacity can cause excessive heat buildup, leading to thermal runaway. This can cause the battery to catch fire or explode. Overheating. High temperatures can destabilise the chemical structure of the battery, potentially leading to a thermal runaway.
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.
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.
When a lithium-ion battery is overcharged, it can lead to the formation of metallic lithium on the battery’s anode. This can cause internal short-circuits, overheating, and, ultimately, a violent explosion. Over-discharging, on the other hand, happens when a battery is depleted beyond its safe limit.
Lithium battery fires typically result from manufacturing defects, overcharging, physical damage, or improper usage. These factors can lead to thermal runaway, causing rapid overheating and potential explosions if not managed properly.
The lithium-ion battery from a Japan Airlines Boeing 787 that caught fire in 2013. Most lithium-ion battery fires and explosions come down to a problem of short circuiting. This happens when the plastic separator fails and lets the anode and cathode touch. And once those two get together, the battery starts to overheat.
