  • Publication number: 20170144345
    Abstract: Disclosed herein are methods and systems for the preparation of a co-injection molded multilayer plastic article. Some methods include co-extruding a combined polymeric stream having an interior core stream encased by an inner stream and an outer stream. A volumetric ratio of the inner stream to outer stream is adjusted during injection of the combined stream into the a mold cavity to alter a streamline along which the interior core stream flows thereby forming cohesion member that structurally interlocks the interior layer with the inner layer, with the outer layer or with both. Some embodiments reduce or eliminate a need for addition of an adhesive in the composite stream to prevent delamination of layers of the resulting multilayer plastic article. In some embodiments, cohesion members may be employed to produce a desired cosmetic effect in a resulting article.

  • Patent number: 9598789
    Abstract: The present invention relates to a method for lithiation of an intercalation-based anode or a non-reactive plating-capable foil or a reactive alloy capable anode, whereby utilization of said lithiated intercalation-based anode or a plating-capable foil or reactive alloy capable anode in a rechargeable battery or electrochemical cell results in an increased amount of lithium available for cycling, and an improved reversible capacity during charge and discharge.

  • Publication number: 20160380262
    Abstract: This method enables the use of nanowire or nano-textured forms of Polyaniline and other conductive polymers in energy storage components. The delicate nature of these very high surface area materials are preserved during the continuous electrochemical synthesis, drying, solvent application and physical assembly. The invention also relates to a negative electrode that is comprised of etched, lithiated aluminum that is safer and lighter weight than conventional carbon based lithium-ion negative electrodes. The invention provides for improved methods for making negative and positive electrodes and for energy storage devices containing them. The invention provides sufficient stability in organic solvent and electrolyte solutions, where the prior art processes commonly fail. The invention further provides stability during repetitive charge and discharge. The invention also provides for novel microstructure protecting support membranes to be used in an energy storage device.

  • Patent number: 7458827
    Abstract: Electrical connectors are adapted to provide a reliable electrical connection to mating elements of a mating connector. The connector can have sockets that accept mating elements of the mating connector. Conductors of the connector are associated with each socket and make electrical contact with mating elements received therein. A loading band of the connector is tensioned to provide a contact force between the conductor and the mating element when the mating connector is in the socket. Electrical connectors constructed in this manner can provide increased current density and/or a more reliable connection between the conductors and the mating element.

  • Patent number: 7223111
    Abstract: An electrical connector that has an array of conductors each having a contact point to make contact with a mating conductive surface. Upon engaging the contact points in a sliding manner with the mating surface, the conductors are displaced, which, in turn, tensions a loading fiber within the connector. Tensioning of the loading fiber provides a contact force between the contact points and the mating surface.
