ABSTRACT:
An alkali metal/solid cathode electrochemical cell, particularly a Li/CF.sub.x cell, having an electrolyte-to-cathode (E/C) weight ratio of about 0.94 to 0.96, and an anode-to-cathode (A/C) capacity ratio of about 1.03, is described. These ratios provide the cell with an improvement of about 6.7% in terms of volumetric energy density and about 11.9% in terms of gravimetric energy density over prior art Li/CF.sub.x cells.
