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 cover. 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.
