  • Patent number: 8703331
    Abstract: A secondary battery including an intermediate layer having a pattern formed by carbon and a binder between a substrate and an active material layer and reinforcing adhesion between the substrate and the active material layer. In the intermediate layer, the carbon and the binder in the intermediate layer are adjacent to each other. Therefore, the active material is prevented from being detached from the substrate, thereby improving performance of the secondary battery. A small amount of the binder having strong adhesion is used in the active material slurry, thereby ensuring safety of the battery.

    Abstract: A conductive film includes a layer 1 formed by a conductive material 1 that includes a polymer material 1 containing any of (1) an amine and an epoxy resin (where the epoxy resin and the amine are mixed in a ratio of 1.0 or more in terms of the ratio of the number of active hydrogen atoms in the amine with respect to the number of functional groups in the epoxy resin), (2) a phenoxy resin and an epoxy resin, (3) a saturated hydrocarbon polymer having a hydroxyl group, and (4) a curable resin and an elastomer and conductive particles 1. The conductive film has excellent stability in an equilibrium potential environment in a negative electrode and low electric resistance per unit area in the thickness direction. A multilayer conductive film including the conductive film achieves excellent interlayer adhesion, and using them as a current collector enables the production of a battery satisfying both weight reduction and durability.

  • Patent number: 8663833
    Abstract: Embodiments of a battery taught herein are directed to preventing a displacement between bipolar battery stacks or between a bipolar battery stack and an electrode tab. A bonding portion is formed at a part of a contact surface where a collector positioned at both ends in a stacking direction of a bipolar battery stack is bonded to the electrode tabs. The electrode tab and the collector are fixed by such a bonding portion. Further, the bonding portion is formed at a part of a contact surface where adjacent bipolar battery stacks are bonded to each other. Bipolar batteries positioned at upper and lower portions in the stacking direction are fixed by such a bonding portion.

  • Publication number: 20140030636
    Abstract: In general, in one aspect, a graphene film is used as a protective layer for current collectors in electrochemical energy conversion and storage devices. The graphene film inhibits passivation or corrosion of the underlying metals of the current collectors without adding additional weight or volume to the devices. The graphene film is highly conductive so the coated current collectors maintain conductivity as high as that of underlying metals. The protective nature of the graphene film enables less corrosion resistant, less costly and/or lighter weight metals to be utilized as current collectors. The graphene film may be formed directly on Cu or Ni current collectors using chemical vapor deposition (CVD) or may be transferred to other types of current collectors after formation. The graphene film coated current collectors may be utilized in batteries, super capacitors, dye-sensitized solar cells, and fuel and electrolytic cells.

  • Patent number: 8632901
    Abstract: A stacked battery has at least two cell segments arranged in a stack. Each cell segment may have a first electrode unit having a first active material electrode, a second electrode unit having a second active material electrode, and an electrolyte layer between the active material electrodes. One or more gaskets may be included in each cell segment to seal the electrolyte within the cell segment. The electrode units may be “dish shaped” and may contain a pressure equalization valve to reduce electrode unit deflection and improve pressure equalization between cell segments. The pressure equalization valve may allow a gas to diffuse through adjacent cell segments and may substantially prevent electrolyte from diffusing through.

    Abstract: A method of joining a substrate for a bipolar electrode of a bipolar battery to a frame for supporting the bipolar electrode for use in the bipolar battery includes the implanting of a thermoplastic material in the substrate. The substrate and the frame are then vibration welded together at a frequency in the range of 50 Hz to 1 kHz to melt the thermoplastic material. The melted thermoplastic material forms a continuous or substantially continuous loop around the substrate to join the substrate and the frame together. A bipolar battery comprising a substrate and a frame joined together by the method, and a substrate for a bipolar electrode for use in the method are also described.
