Enhanced capacity Li/CFx electrochemical cell

1. Field of the Invention An alkali metal/solid cathode electrochemical cell, particularly a Li/CFcell, having an electrolyte-to-cathode (E/C) weight ratio of about 0.938 to about 0.73, and an anode-to-cathode (A/C) capacity ratio of about 1.03, is described. This provides the cell with an improveme...

Summary:1. Field of the Invention An alkali metal/solid cathode electrochemical cell, particularly a Li/CFcell, having an electrolyte-to-cathode (E/C) weight ratio of about 0.938 to about 0.73, and an anode-to-cathode (A/C) capacity ratio of about 1.03, is described. This provides the cell with an improvement in terms of delivered capacity of about 6% to about 15% under a 1 kohm discharge load, and of about 2% to about 5% under a 2 kohm load in comparison to prior art Li/CFcells. Fabricating the cathode electrode at such high pressures was not previously thought possible.
