Patent ID: 7776470

Claim:
An electrochemical cell, which comprises: a) an anode of lithium having an anodic coulombic capacity; b) a cathode comprising the configuration: silver vanadium oxide (SVO)/first current collector/fluorinated carbon (CF x ), wherein in a freshly built cell, a ratio of the anodic coulombic capacity to the total coulombic capacities of SVO and CF x is in a range of: [0.80(M CFx ×Q CFx )+0.40(M SVO ×Q SVO )]<Q anode <[(M CFx ×Q CFx )+(M SVO ×Q SVO )]×1.25, wherein M CFx =the mass of CF x in grams, M SVO =the mass of SVO in grams, Q CFx =the capacity of CF x in mAh, Q SVO =the capacity of SVO in mAh, and Q anode =the capacity of the anode in mAh; c) a separator disposed between the anode and cathode to prevent direct physical contact between them; and d) a nonaqueous electrolyte activating the anode and the cathode.
