Abstract: A cathode produced from a new process for manufacturing a cathode component from a free-standing sheet of cathode material, is described. The process comprises a first step of adjusting the particle size of the cathode active material to a useful size followed by mixing with binder and conductive additives suspended in a suitable solvent to form a paste. The paste is then fed into a series of roll mills to form the sheet material, or the paste can first be pelletized before the rolling step. The cathode sheet material is dried and punched into cathode plates having a myriad of geometric shapes suitable for cathode preparation by compressing a current collector between two plates of the cathode material.

Abstract: A structure for stabilizing of an electrochemical cell stack against high shock and vibration forces through the use of a plurality of electrode connections at both the top and bottom of the stack is described. Constructing the cell casing having a tubular shape rather than the typical deep drawn can shape, allows access to the lower portion of the stack. There, additional leads are welded to the cell case, which significantly adds to the stability of the stack within the case. The lower portion of the case is then within the case. The lower portion of the case is then hermetically sealed by fitting and welding a disc in place.

Abstract: A method for manufacturing electrochemical cells having a low electrochemical surface, from standard electrodes used in cells having a high electrochemical surface, includes configuring the standard electrodes by folding one or more of the standard electrodes to reduce the overall length, and hence the electrochemical surface area to a fraction of that of the unfolded standard electrode. A cell stack is assembled by placing the folded electrode and a standard electrode, or alternatively a folded cathode and a folded anode, in a face-to-face relationship with a separator therebetween.

Abstract: 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.

The first cathode active material has a first energy density and first rate capability, and the second cathode active material has a second energy density and a second rate capability. The first energy density of the first material is less than the second energy density of the second material, while the first rate capability of the first material is greater than the second rate capability of the second material.

Abstract: Heat generation is an important concern of electrochemical cell design. The invention is directed toward a cell design that efficiently and responsively dissipates heat by transfer from the cell to the casing through multiple parallel connections. This invention relates to battery designs having cell stacks in which both the anode and cathode are of a plate structure and the anode plates are independently connected to the cell casing or connected thereto via a bridge or bus. They may also consist of cell assemblies of wound electrode configurations or plate-serpentine configurations having multiple parallel connections to the cell casing.
