Electric batteries - Activatable batteries

The advantage of activatable batteries is their total inertia in the non-activated state. But once activated, these batteries must be used, or they will be irretrievably lost. The magnesium-silver chloride battery family, involving contact with seawater, has applications mainly in the maritime sector. Thermal batteries (calcium-calcium chromate and lithium-iron disulphide), as well as lead-lead dioxide batteries, feature rapid activation and are recommended for systems such as smart ammunition, ejector seats and airbags.
