Abstract
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.
