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 hermetically sealed coin cell is described. The coin cell has the opposite polarity terminals isolated from one another by a glass-to-metal seal. Glassing a conductive disc inside a ring of greater diameter and height forms this seal. The height of the ring is equivalent to the desired height of the cell. The disc acts as one cell terminal, which can be positive or negative, and the ring serves as the other terminal. In plan view, both terminals are on the same side of the cell. This allows for easy mounting and connection to an electric circuit board, and the like.

摘要： It is known that reforming implantable defibrillator capacitors at least partially restores and preserves their charging efficiency. An industry-recognized standard is to reform implantable capacitors by pulse discharging the connected electrochemical cell about once every three months throughout the useful life of the medical device. A Li/SVO cell typically powers such devices. The present invention relates to methodologies for significantly minimizing, if not entirely eliminating, the occurrence of voltage delay and irreversible Rdc growth in the about 25% to 70% DOD region by subjecting Li/SVO cells to novel discharge regimes. At the same time, the connected capacitors in the cardiac defibrillator are reformed to maintain them at their rated breakdown voltages.

摘要： A new sandwich cathode design is provided having a first cathode structure of a first cathode active material of a relatively low energy density but of a relatively high rate capability, for example SVO, mixed with a second cathode active material having a relatively high energy density but a relatively low rate capability, for example CFx, with the percentage of SVO being less than that of CFx and sandwiched between two current collectors. Then, a second cathode mixture of SVO and CFx active materials is contacted to the outside of the current collectors. However, the percentage of SVO to CFx is greater in the second structure than in the first. Such an exemplary cathode design might look like: (100−y)% SVO+y% CFx, wherein 0≦y≦100/current collector/(100−x)% SVO+x% CFx, wherein 0≦x≦100/current collector/(100−y)% SVO+y% CFx, wherein 0≦y≦100, and wherein the ratio of x to y is selected from the group consisting of y
