Abstract: A miniature electrochemical cell having a volume of less than 0.5 cc is described. The cell casing comprises an open-ended ceramic container having a via hole providing an electrically conductive pathway extending through the container. A metal lid closes the open-end of the container. An electrode assembly housed inside the casing comprises an anode current collector deposited on an inner surface of the ceramic container in contact with the electrically conductive pathway in the via hole. An anode active material contacts the current collector and a cathode active material contacts the metal lid. A separator is disposed between the anode and cathode active materials. That way, the electrically conductive pathway serves as a negative terminal, and the lid, electrically isolated from the conductive pathway by the ceramic container, serves as a positive terminal. The negative and positive terminals are configured for electrical connection to a load.

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 ceramic casing halves. The two ceramic casing halves are separated from each other by a metal interlayer, such as of gold, bonded to a thin film metallization adhesion layer, such as of titanium, that contacts an edge periphery of each ceramic casing half. A solid electrolyte (LixPOyNz) is used to activate the electrode assembly.

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: 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.

Abstract: A miniature electrochemical cell having a volume of less than 0.5 cc is described. The cell casing comprises an open-ended ceramic container having first and second via holes providing respective first and second electrically conductive pathways extending through the container. A metal lid secured to the open-end of the container by a gold seal provides the cell casing. An electrode assembly housed inside the casing comprises a cathode active material deposited on an inner surface of the ceramic container in contact with a current collector in electrical continuity with one of the conductive pathways. A solid electrolyte, preferably of LiPON (LixPOyNz), is deposited on the cathode active material followed by an anode active material in contact with the other conductive pathway. The first and second conductive pathways can comprise platinum or gold. That way, the first and second conductive pathways serve as negative and positive terminals for the cell. The negative and positive terminals are configured for electrical connection to a load.

Abstract: A miniature electrochemical cell of a secondary chemistry having a total volume that is less than 0.5 cc is described. Before the present invention, miniature secondary electrochemical cells have been known to experience undesirable open circuit voltage discharge during their initial 21-day aging period. It is believed that electrolyte permeating through the cathode active material and an intermediate carbonaceous coating contacting the titanium base plate of the casing is the source of the undesirable discharge. To ameliorate this, aluminum is contacted to the inner surface of the base plate inside the casing. While aluminum is resistant to the corrosion reaction that is believed to be the mechanism for degraded open circuit voltage in miniature secondary electrochemical cells containing lithium, it is not biocompatible. This means that titanium is still a preferred material for the casing parts including the base plate that might be exposed to body fluids, and the like.
