  • Patent number: 5495250
    Abstract: An RF tag (20) includes a low profile battery power source (22). The RF tag includes an electrically insulating substrate 21, an RF transmitter (24) on the substrate for transmitting a predetermined identification code, and the battery (22). The battery includes a first pattern of conductive material to form a planar anode structure (48) and a second pattern of conductive material on the substrate to form a cathode structure (50). A protective layer (92) overlies the substrate. The protective layer includes an opening (94) to expose the anode and cathode of the battery to permit an electrolyte to be applied to the anode and cathode for completing the formation of the battery and to provide electrical energy to the RF transmitter. A manufacturing apparatus (60) is also described which permits the RF tags to be manufactured in a low cost, reel-to-reel, basis. Also described is a dispenser (100) for activating and dispensing the RF tags one at a time at a point of use.

  • Patent number: 5350645
    Abstract: Improved polymer batteries and improved methods of manufacturing such polymer batteries are provided. One improved method of manufacture involves the formation of a laminated array structure that includes a number of individual battery cells. After formation of the laminated array the individual batteries are singulated from the array by cutting, shearing or stamping. Other manufacturing improvements include the use of a printing process (e.g. stenciling) to form the cathodes, the use of permanent mask layers to contain and insulate the cathodes and anodes, and the use of a molten lithium deposition process for forming the anodes.

  • Patent number: 5147985
    Abstract: Using sheet battery material as a circuit board substrate eliminates the weight and bulk of batteries as a separate circuit component and also eliminates the weight and bulk of fiberglass substrate or flex substrate as printed circuit materials. Insets with wiring built in can give vertical wiring between two or more circuit layers and can support electronic components which have leads connecting wiring on more than one layer of a printed circuit. Connector clips inserted when the connector pins are polarized target connection to power and to ground components of one or more layers of sheet battery. Using these connections between battery substrate components of the structure allows a single power source as A-C or solar to recharge all battery substrate in the electronic component.

  • Patent number: 5035965
    Abstract: Disclosed herein is a thin film cell in which a cell unit is sealed by a polyamide film. Such a cell unit can be obtained by forming an ion-conductive polymer electrolytic layer formed by mixing polyethylene oxide derivatives with lithium salt on a negative-polarity material composed of lithium or a lithiumaluminum metal foil and then forming a layer of a positive-polarity material from composite materials formed by mixing Vanadium oxide and polyethylene oxide derivatives together, on the electrolytic layer, by using a screen printing process. Also disclosed is a printed circuit board with a thin film cell incorporated therein, in which said cell unit is to be mounted on a flexible film substrate, by using a screen printing process. By this invention, the thin film cell and the printed circuit board can be fabricated in a continuous manner by making use of a screen printing process.

  • Patent number: 4730383
    Abstract: This invention relates to a process for producing a solid state battery successively comprising, superposed between two metallic contact elements, a layer or thin film of an alkali metal such as lithium, constituting a source of ions, a layer or thin film of a superionic solid electrolyte and a layer or thin film of a layered intercalation compound capable of inserting ions issued from the alkali metal film. The lamellae of the film of layered compound are oriented so that their c-axis is substantially parallel to the surface of the solid electrolyte. The process consists essentially in making the layer or thin film of layered compound by direct grafting on the film which is to serve as substrate therefor, on which is initially impressed a grating which conditions the nucleation starting the crystal growth by means of the techniques of molecular beam deposition. The invention also relates to a battery made in accordance with this process.

  • Patent number: 4645943
    Abstract: A space-saving back-up power supply apparatus has length and width dimensions substantially the same as those of a conventional integrated circuit connector. The apparatus includes sockets arranged on its top for making connection to a socket-pluggable integrated circuit such as a standard CMOS RAM, and the apparatus has pins extending from its bottom for making connection to a printed circuit board or connector of a host electronic system. Control circuitry and one or more batteries are located within the apparatus. The back-up power supply is operative to provide power to the socket-pluggable integrated circuit even if the normal power supply of the host electronic system is short-circuited. The control circuitry of the back-up power supply controls the chip enable signal and performs a battery test upon power-up.

  • Patent number: 3979222
    Abstract: An electrochemical storage cell is formed by connecting up elements in hydraulic and electric series and, in each of the elements, in electrically insulating the inside of the negative end fitting situated hydraulically the nearest to the following element. In this way, the interference transfer of charges resulting from the electric series connection of two neighbouring elements can be effected only by ionic conduction in the electrolyte flowing between the two elements. The invention is used in air-zinc cells.
