6 FAQs about [Explosion-proof certified battery short-circuit current]
What are external short circuit (ESC) faults in lithium-ion batteries?
External short circuit (ESC) faults pose severe safety risks to lithium-ion battery applications. The ESC process presents electric thermal coupling characteristics and becomes more complex when the batteries operate in large group, which often lead to serious consequences.
Can lithium ion cells explode in a short circuit?
The standard warns that some types of lithium-ion cells may explode in the event of a short circuit. The standard also describes a short-circuit test with an external short-circuit resistance of just 3 mΩ. In this test, the cell must not be protected by external circuitry.
What happens after a short circuit in a lithium ion battery?
Following the short circuit, the capacity of the undamaged battery was returned to its original level. Potential heat risks inside batteries after a short circuit are investigated. External short circuit is a common phenomenon triggering thermal runaway in Li-ion battery.
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 happens if a battery has a secondary short circuit?
When the undamaged batteries in first short circuit process experienced a secondary short circuit, the batteries exhibited a larger voltage drop, faster temperature rise rate and a higher temperature rise than fresh one.
What is ESC experimentation on batteries?
Different degrees of ESC experimentation on batteries are carried out. The electro-thermal properties of ESC batteries are analyzed. The structural alterations of an electrode in a short-circuit battery are examined. Following the short circuit, the capacity of the undamaged battery was returned to its original level.
