Why do lithium-ion batteries catch fire?
Lithium-ion batteries (LiBs) are energy-dense and contain material that is highly flammable. The risks and hazards associated with LiBs include fire and explosion, radiation, heat, chemical and electrical.
There are several situations that can lead to lithium-ion batteries catching fire, including:
overcharging or use of non-compliant charging equipment
overheating or exposure to heat or extreme temperatures
physical abuse (e.g., dropping, crushing, piercing, and/or vibrations)
short-circuiting, battery cell malfunctions or system faults
defects or contamination introduced during manufacture.
The end users have no control over the last two as in the case in the video
