A high efficiency pyrotechnically activated lithium-chlorine primary cell ving a high voltage output, high energy density, and a high rate of discharge comprises a porous graphite gas diffuser, a fused alkali metal salt electrolyte, a lithium anode in contact with the electrolyte, a lithium vapor barrier, and a cartridge containing a pyrotechnic material disposed within the anode, all of the components being stacked inside a container which serves as the cell case. The lithium vapor barrier comprises a porous metal ring impregnated with lithium-chloride and is designed to prevent vaporized lithium from penetrating the barrier, contacting the chlorine cover gas and exothermically reacting.

A pyrotechnically activated lithium-chlorine cell possessing high voltage, igh energy density and a high rate of discharge is composed of a porous graphite gas diffuser, a fused alkali metal salt electrolyte, a lithium anode in contact with the electrolyte, and a cartridge containing a pyrotechnic material disposed within the anode, all of the components being stacked inside a container that serves as the cell case. The porous gas diffuser is positioned within the cell case to provide a gas receiving chamber. Chlorine is introduced into the gas receiving chamber as the pyrotechnic material is ignited to activate the cell.
