A small, portable electrochemical power cell, having an output voltage of over 4 V, and preferably over 5 V, includes an anode, a cathode having a fluorine compound and an electrolyte having an organic sulfur-containing compound to maintain ionic conductivity between the anode and the cathode. A method of fabricating such an electrochemical power cell includes the step adding an electrolyte having an organic, sulfur-containing compound to maintain electrical conductivity between the anode and the cathode. An electrochemical power cell having a lithium anode, a CoF,cathode, an electrolyte to maintain ionic conductivity between the anode and the cathode and a cobalt complexing material within the electrolyte to complex cobalt ions is described.

Electrochemical power cells and method of improving electrochemical power cell performance

A small, portable electrochemical power cell, having an output voltage of over 4 V, and preferably over 5 V, includes an anode, a cathode comprising a fluorine compound and an electrolyte to maintain ionic conductivity between the anode and the cathode. A method of fabricating such an electrochemical power cell includes the step of adding a fluorine compound to the cathode and/or to the electrolyte solvent.

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.
