Chemical information on propulsion batteries

Under normal conditions, the chemicals are enclosed in so-called cells within
the propulsion battery. The chemicals cannot leak out into the surrounding
area. The cells usually contain a combination of a liquid and some solid
materials. The liquid in the cells is firmly bonded to the materials.
There is a risk of contact when the contents are converted to gas and vent out
of the cell. This can occur in the event of external damage to one or more cells,
in the event of too high a temperature or overload. When a cell has been
opened or damaged, the electrolyte may be exposed. Exposed electrolytes are
converted to a gaseous state at room temperature. This gas is flammable.
The liquid within the cells is flammable and can be corrosive if it comes into
contact with moisture. If damage occurs and the battery starts to emit steam or
mist, this may irritate mucous membranes, airways, eyes and skin. Exposure
can also cause dizziness, nausea and headache.
Undamaged cells in a battery can handle up to 80° Celsius before starting to
ventilate. If the temperature in the cells is greater than 80° Celsius, the
electrolyte in the cell starts to change into a gas. This may cause the pressure
relief value in the cells to break, and flammable and corrosive gas is released
via the battery pack ventilation duct.
