Serious Consequences of Battery Thermal Runaway
Thermal runaway is an autocatalytic process that triggers uncontrollable exothermic reactions when battery temperature rises to a certain level.
This phenomenon can lead to the following serious consequences:
Toxic Gas Release:
During thermal runaway, batteries may release toxic gases such as hydrogen fluoride (HF), posing serious threats to human health.
Fire and Explosion Risk:
Rapid temperature rise may cause battery ignition and even lead to explosions.
Chain Reaction:
In large-scale energy storage facilities or electric vehicle battery packs, thermal runaway of one battery may trigger a chain reaction in adjacent batteries, causing more extensive disasters.
Environmental Pollution:
Toxic smoke from fires may have long-term impacts on the surrounding environment.
When lithium batteries burn, they release various toxic gases, mainly including:
- Hydrogen Fluoride (HF):
Hydrogen fluoride is one of the primary toxic gases produced during lithium battery combustion.
It has strong irritant and corrosive properties that can cause severe respiratory damage, ranging from asthma to pulmonary failure.
- Carbon Monoxide (CO):
Carbon monoxide is another common toxic gas that affects blood oxygen-carrying capacity.
- Hydrogen Cyanide (HCN):
Some studies have detected hydrogen cyanide release during lithium battery combustion, which is a highly toxic gas.
- Phosphoryl Fluoride (POF3):
Phosphoryl fluoride is an extremely toxic gas detected in certain lithium battery combustion tests.
- Other Toxic Gases:
Additionally, sulfur dioxide (SO2), nitrogen oxides (NOx), and other toxic gases may be produced. - Flammable Gases:
Besides toxic gases, lithium battery combustion also releases hydrogen, methane, and other flammable gases, increasing fire and explosion risks.
