• External fire: Internal pressure and thermal runaway may be the consequences if the
cells inside the battery are exposed to temperatures above 85 °C.
• Internal short circuit: Internal short circuit in a cell. Destruction of the separator can
cause a short circuit between the anode and cathode. Thermal runaway and fire is
possible.
• Water ingress: Internal pressure, thermal runway and chemical reactions may be
the consequence.
The transponder is fitted with a pressure relief valve at the bottom of the unit. The
relief valve prevents overpressure. Noxious gases and ingredients will then leak out of
the transponder until the chemical reactions have stopped. Products generated by the
chemical reactions during an emergency may however clog this pressure release valve.
SECTION 3: Composition
The battery is a solid, manufactured article.
A lithium battery pack consists of several individual cells that are electrical connected,
both in series and parallel.
The battery packs have different number of cells and power capacity. All transponder
batteries include protection against short circuits (circuit breakers) and reverse current
(diodes).
The lithium metal cells have the following chemical formula:
Lithium thionyl chloride — Li/SOCl
