Lithium-Ion Battery
How do Lithium-Ion Battery Fires Occur?
In the era of portable electronics and electric vehicles, lithium-ion batteries have become an integral part of our daily lives. While these batteries offer exceptional energy density and efficiency, it's crucial to acknowledge and address the potential risks associated with them, particularly the occurrence of lithium-ion battery fires.
Lithium-ion battery fires typically result from a phenomenon known as "thermal runaway." This occurs when a battery's internal temperature rises uncontrollably, leading to a cascade effect of increased heat generation. The factors contributing to thermal runaway include:
-
Overcharging: Excessive charging voltage or prolonged charging periods can cause the battery to overheat.
-
Physical Damage: Any physical damage to the battery, such as punctures or crushing, can compromise its integrity and trigger thermal runaway.
-
Manufacturing Defects: In rare cases, manufacturing defects may lead to internal short circuits, initiating thermal runaway.
The Dangers of Lithium-Ion Battery Fires:
-
Rapid Escalation: Lithium-ion battery fires can escalate rapidly, releasing toxic fumes and generating intense heat.
-
Explosive Potential: In extreme cases, thermal runaway can lead to an explosive release of energy, posing serious risks to people and property.
-
Environmental Impact: Improper disposal of damaged batteries can contribute to environmental pollution due to the chemicals released during combustion.
