Thermal Battery/lithium batteries

A thermal battery is an exceptionally reliable source of specific energy. It is a non-rechargeable, single use battery that is completely inert before being activated. It can be stored without requiring maintenance for more than 15 years and then brought into use at any time, requiring only several tenths of a second before it is ready for use. Activation is effected internally either by mechanical or electrical ignition. Certain batteries can also be activated automatically, for example through an accelerating effect or a sudden increase in temperature. It can function under severe climatic and mechanical environments. Its intrinsic qualities mean that it is impervious to high stresses, sudden shocks and sharp pressure drops.
