Abstract
An electrochemical cell includes an active element having an anode including carbon, a cathode including a metal oxide, a separator between the anode and the cathode, and an electrolyte disposed between the anode and the cathode. The anode, cathode, and separator are preferably in planar form rolled into a spiral. There is a sealed housing having an interior in which the active element is received, and a gas filling a gas space of the sealed housing. The gas has from about 10 to about 100 percent by volume of the conductive gas hydrogen, helium, and/or neon, or mixtures thereof.

An electrochemical cell comprising:
- an active element, comprising
- an anode comprising carbon,
- a cathode comprising a metal oxide,
- a separator between the anode and the cathode, and
- an electrolyte disposed between the anode and the cathode;
- a sealed housing having an interior in which the active element is received;
- and
- a gas filling a gas space of the sealed housing, which is a remainder of the interior of the sealed housing that is not filled by the active element, the gas comprising from about 10 to about 100 percent by volume of a conductive gas selected from the group consisting of hydrogen and neon, and mixtures thereof.
An electrochemical cell comprising:
- an active element, comprising
- a planar anode comprising carbon particles supported on a metallic anode current collector,
- a planar cathode comprising metal oxide particles supported on a metallic cathode current collector,
- a planar separator between the anode and the cathode, wherein the anode, the cathode, and the separator are wound into a spiral, and
- an electrolyte disposed between the anode and the cathode;
- a sealed metallic housing having an interior in which the active element is received;
- and
- a gas filling a gas space of the sealed housing, which is a remainder of the interior of the sealed housing that is not filled by the active element, the gas comprising from about 10 to about 100 percent by volume of a conductive gas selected from the group consisting of hydrogen and neon, and mixtures thereof.
