摘要： A solid cathode liquid organic electrolyte lithium cell for delivering high current pulses comprising a casing, a cathode structure inthe casing comprising a plurality of plates in spaced apart relation, a lithium anond comprising a plurality of anode sections interposed between the cathode plates, a non-aqueous liquid organic electrolyte comprising the combination of a lithum dalt and an organic solvent in the casing operatively contacting the anode and the cathode an electrical connection provided to the anode and an electrical connection provided to the cathode. In accordance with one aspect of the invention the cathode includes as active material Ag.sub.x V.sub.2 O.sub.y where x is in the range from about 0.5 to about 2.0 and y is in the range from about 4.5 to about 6.0 which advantageously has high volumetric capacity and high rate capability with the result that the cell of the present invention delivers high capacity, shows good current pulsing behavior at various levels of discharge, and has a sloping discharge cause enabling end of life to be predicted. In accordance with another aspect of the present invention, the anode comprises a continuous elongated lithium element enclosed within a separator and folded into a plurality of sections interposed between the cathode plates, each of which individually is enclosed within separator material thereby enhancing the reliability of the cell. The cell of the present invention finds advantageous use as a power source for an implantable cardiac defibrillator.
