Potential danger of damaged battery:
Chemical Hazard: Despite of its careful and professional protection design against any
hazard results, rupture of battery shall still occur due to mechanical damage, internal
pressure etc., and may result in a leakage of battery electrolyte. The electrolyte is
corrosive and flammable. When there is fire, the toxic gases produced will cause skin
and eyes irritation, and discomfort after inhalation. Therefore:
1) Do not open damaged batteries.
2) Do not damage the battery again (shock, fall, trample, etc.).
3) Keep damaged batteries away from water (except to prevent an energy storage
system from catching fire).
4) Do not expose the damaged battery to the sun to prevent internal heating of the
battery.
Electrical hazard: The reason of fire and explosion accidents in lithium batteries is
battery explosion. Here are the main factors of battery explosion:
1) Short circuit of battery. Short circuit will generate high heat inside battery, resulting
in partial electrolyte gasification, which will stretch the battery shell. The
temperature reaching ignition point of internal material will lead to explosive
combustion.
2) Overcharge of battery. Overcharge of battery may precipitate lithium metal. If the
shell is broken, it will come into direct contact with the air, resulting in combustion.
The electrolyte will be ignited at the same time, resulting in strong flame, rapid
expansion of gas and explosion.
