Abstract: The traditional method of pressing CFx, screen and SVO sheet assembly results in an electrode that is cupped and not flat. This results in the reduction of the effective volumetric energy density of the electrode or the addition of a process step of flattening of the cathode if at all possible. The new method of assembly effectively eliminates the cupping behavior and produces a flat electrode. In addition, the physical density of the cathode is also increased.

Abstract: The current invention describes a lithium/carbon monofluoride (Li/CFx) cell capable of delivering sufficient power to supply an ICD or similar demanding device. The cell exhibits the typical excellent long-term stability and predictability of the CFx system, as well as its high energy density (greater than about 300 Ah/cc, greater than about 600 Wh/cc). Additionally, the cell is capable of delivering about 0.5 W/cc of cathode volume for greater than 5 seconds with a voltage above 1.70 V (FIG. 1). The following invention embodiments can be applied individually or in conjunction with each other.

Abstract: A mesh (36) is placed around a bundle (32) of fused glass fibers. The bundle is then immersed in a leaching bath (44). The ends of the bundle are protected from the bath fluid by furrules (34). Some of the glass of the bundle is leached out, so as to provide a flexible fiber bundle.

Abstract: Improvements in the performance of lithium electrochemical cells comprising a first cathode active material of a relatively high energy density but of a relatively low rate capability, for example CFx, contacted to one side of a current collector and with a second cathode active material having a relatively low energy density but of a relatively high rate capability, for example SVO, contacted to the opposite current collector side are described. An exemplary cathode has the configuration: SVO/first current collector/CFx/second current collector/SVO, and wherein the anodic coulombic capacity does not exceed the total coulombic capacities of the SVO and CFx by greater than 25%. Manganese oxide (MnO2) is another typically used cathode active material in lieu of SVO, and the present invention is applicable to lithium cells of that system as well.

Abstract: A new design for a cathode having a configuration of: SVO/first current collector/CFx/second current collector/SVO is described. The two cathode current collectors are vertically aligned one on top of the other in a middle region or zone of the cathode. This coincides to where a winding mandrel will be positioned to form a wound electrode assembly with an anode. The overlapping region of the two current collectors helps balance the expansion forces of the exemplary SVO and CFx active material layers. This, in turn, helps maintain a planar cathode that is more amenable to downstream processing. The use of two current collectors on opposite sides of an intermediate cathode active material also provides for enhanced reliability when cathodes are wound from the center as they lend structural integrity to outer portions of the wind.

Abstract: 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 electronic circuit board, and the like.
