摘要： An electrochemical cell comprising a lithium anode, a cathode comprising a blank cut from a free-standing sheet of a silver vanadium oxide mixture contacted to a current collector. The active material has having a relatively lower surface area and an electrolyte activating the anode and the cathode is described. By optimizing the cathode active material surface area in a SVO-containing cell, the magnitude of the passivating film growth at the solid-electrolyte interphase (SEI) and its relative impermeability to lithium ion diffusion is reduced. Therefore, by using a cathode of an active material in a range of from about 0.2 m2/gram to about 2.6 m2/gram, and preferably from about 1.6 m2/gram to about 2.4 m2/gram, it is possible to eliminate or significantly reduce undesirable irreversible Rdc growth and voltage delay in the cell and to extend its useful life in an implantable medical device.

摘要： A method for determining whether a cell will experience unacceptable voltage delay later in its discharge life before it is incorporated into a device as its power source is described. As is standard practice, the cell is first subjected to a constant resistance load discharge followed by extended elevated temperature storage and an acceptance pulse discharge. This typically depletes the cell of about 1% to 3% of its theoretical discharge capacity. According to the present invention, the cell is again stored at an elevated temperature for an extended period followed by a second pulse discharge. This second pulse discharge is to ferret out any cell that may end up experiencing unacceptable voltage delay later in its discharge life.
