Abstract: A miniature electrochemical cell having a total volume that is less than 0.5 cc is described. The cell casing is formed by joining two ceramic casing halves together. One or both casing halves are machined from ceramic to provide a recess that is sized and shaped to contain the electrode assembly. The opposite polarity terminals are metal feedthroughs, such as of gold, and are formed by brazing gold into openings machined into one or both of ceramic casing halves. A thin film metallization, such as of titanium, contacts an edge periphery of each ceramic casing half. The first ceramic casing half is moved into registry with the second ceramic casing half so that the first and second ring-shaped metallizations contact each other. Then, a laser welds through one of the casing halves being a substantially transparent ceramic, for example sapphire, to braze the first and second ring-shaped metallizations to each other to thereby join the first and second casing halves together to form a casing housing the electrode assembly. A solid electrolyte (LixPOyNz) activates the electrode assembly.

Abstract: An electrochemical cell comprising a cathode and an anode residing within a casing, the anode being positioned distal of the cathode. The cathode having a cathode current collector having an angled configuration that encourages the cathode active material to move in an axial distal direction during cell discharge. The cathode current collector may be configured having at least one fold thereby dividing the current collector into at least two portions having an angle therebetween. The cathode current collector may comprise a wire having a helical configuration or the cathode current collector may comprise a post with a thread having a helical orientation about the post exterior. A preferred chemistry is a lithium/CFx activated with a nonaqueous electrolyte.

Abstract: A lithium electrochemical cell with increased energy density is described. The electrochemical cell comprises an improved sandwich cathode design with a second cathode active material of a relatively high energy density but of a relatively low rate capability sandwiched between two current collectors and with a first cathode active material having a relatively low energy density but of a relatively high rate capability in contact with the opposite sides of the two current collectors. In addition, a cathode fabrication process is described that increases manufacturing efficiency. The cathode fabrication process comprises a process in which first and second cathode active materials are directly applied to opposite surfaces of a perforated current collector and laminated together. The present cathode design is useful for powering an implantable medical device requiring a high rate discharge application.

Abstract: An electrochemical cell having a casing housing an electrode assembly of a separator residing between a lithium anode and a cathode comprising silver vanadium oxide and fluorinated carbon is described. The electrode assembly is activated with a nonaqueous electrolyte comprising a lithium salt dissolved in a solvent system of propylene carbonate mixed with 1,2-dimethoxyethane, dibenzyl carbonate (DBC), lithium bis(oxalato)borate (LiBOB), and fluoroethylene carbonate (FEC). Preferably DBC is present in an amount ranging from about 0.005 moles (M) to about 0.25M, LiBOB is present in an amount ranging from about 0.005 wt. 5 to about 5 wt. %, and FEC is present in an amount ranging from about 0.01 wt. % to about 10 wt. %. This electrolyte formulation is more conductive than the conventional or prior art binary and ternary solvent system electrolytes while being chemically and electrochemically stable toward Li/SVO cells, Li-SVO/CFx mixture cells, and Li-SVO/CFx sandwich cathode primary electrochemical cells.

Abstract: A miniature electrochemical cell of a primary or secondary chemistry with a total volume that is less than 0.5 cc is described. The cell casing comprises an annular sidewall connected to a base plate opposite an upper lid. A sealing glass forms a hermetic glass-to-ceramic seal with a dielectric material contacting a lower portion of the annular sidewall and a glass-to-metal seal with the base plate. Since the glass seals against three surfaces of the annular sidewall, which are the inner and outer sidewall surfaces adjacent to the lower edge, the glass seal is robust enough to withstand the heat generated when the lid is welded to the upper edge of the annular sidewall. The lid has a sealed electrolyte fill port that is axially aligned with an annulus residing between the inner surface of the annular sidewall and the electrode assembly.
