Potential danger of damaged battery:
Chemical Hazard: Despite of its strict and professional protection design
against any hazard results, rupture of battery shall may still occur due to
mechanical damage, internal pressure and 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 stretches 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.
