What happens if a battery does not have a short circuit?
Firstly, without external short circuit protection, the battery passes a great current for a long time leading to a rapid rise in temperature, which triggers the internal side reaction or even thermal runaway, generating a large amount of smoke, which triggers combustion under the action of electric sparks, as in the result of test 1.
What chemicals are released when a lithium-ion battery emits smoke?
Understanding what chemicals are released when a lithium-ion battery emits smoke requires examining the specific substances that are generated during thermal runaway and combustion. Hydrogen fluoride is a toxic gas released during the thermal decomposition of lithium-ion batteries.
What happens if you smoke lithium ion battery?
This smoke typically contains harmful substances such as heavy metals and organic compounds. Inhaling lithium-ion battery smoke can lead to respiratory issues. The smoke may irritate the lungs and throat, causing coughing and difficulty breathing. It can also trigger asthma and exacerbate existing respiratory conditions.
What are the risks of external short-circuit of battery modules?
The risks of external short-circuit of battery modules with different voltage levels are tested for the first time. Two types of typical risk modes and influencing factors of ESC of battery modules are analyzed and proposed. The effectiveness and limitations of weak links for protection in external short circuits of battery modules are verified.
What causes thermal runaway in a battery?
The main reason for the occurrence of side reaction or even thermal runaway in the external short circuit process of battery is the rapid increase of battery temperature caused by the ESC current, so the magnitude of the ESC current is a key factor affecting the occurrence of thermal runaway.
What are the risks associated with battery thermal runaway reactions?
Even though catastrophic failure is rare, the high socioeconomic risks associated with battery thermal runaway reactions cannot be overlooked, as demonstrated by recent high-profile events.
