ABSTRACT:
An electrochemical cell using a lithium anode and a silver vanadium oxide cathode is provided in which the cell is anode limited. Preferably, only enough lithium and electrolyte are provided in an Li/SVO cell to allow it to discharge only to the start of the second voltage plateau of its discharge curve. This provides a cell with improved performance in implantable defibrillator applications.
