Abstract:
A method for discharging an electrochemical cell, comprising the steps of:a) providing the electrochemical cell comprising: a casing;an anode comprising lithium as an anode active material; anda cathode comprised of silver vanadium oxide as a cathode active material;b) operatively associating the anode with the cathode housed inside the casing with the anode active material and the cathode active material in a maximum anode-to-cathode capacity ratio of 0.68 to about 0.96 based on the gram amount of anode and cathode active materials with a theoretical maximum capacity of 7.0 equivalents of lithium required to completely discharge one equivalent of silver vanadium oxide and wherein the anode and the cathode are connected to respective terminals;c) activating the anode and the cathode with an electrolyte filled into the casing; andd) discharging the cell to the anode-to-cathode capacity ratio of 0.68 to about 0.96.
