Patent ID: 8623553

Claim:
A non-aqueous electrochemical cell comprising: an anode; a cathode comprising a cathode material comprising a mixture of fluorinated carbon, an oxide of copper, and an oxide of manganese; a separator disposed between the anode and the cathode; and, a non-aqueous electrolyte which is in fluid communication with the anode, the cathode and the separator, wherein: the concentration of the fluorinated carbon in the cathode material mixture is between about 60 wt % and about 95 wt %, based on the total weight of the cathode mixture; the fluorinated carbon is a mixture of materials having the formulas (CF x1 )n and (CF x2 )m, where: x1 is between about 0.8 to about 1.2, x2 is between about 0.4 to about 0.8, n is between about 1 to about 5, and m is between about 1 to about 5; (CF x1 )n and (CF x2 )m are distinct materials from each other; a ratio of (CF x1 ) to (CF x2 ) is from about 5:1 to about 1:5; and a ratio of the oxide of copper to the oxide of manganese or a ratio of the oxide of manganese to the oxide of copper is from about 1:1 to 5:1.
