| 20090181294 | Battery Separators and Batteries - Batteries are provided that include a tubular battery separator having a locally strengthened region. The strengthened region maybe provided by including a folded area adjacent an open end of the tubular separator. | 07-16-2009 |
| 20100112431 | SEPARATORS FOR ALKALINE ELECTROCHEMICAL CELLS - The present invention relates to a high capacity electrochemical cell having a cathode containing an oxide of copper as an active material, as well as an anode, an electrolyte, and separators for use with the cathodes of the invention in an alkaline electrochemical cell. | 05-06-2010 |
| 20090148758 | Oxidation resistant separator film for batteries - A separator film for an electric battery is provided to substantially eliminate electric contact between an anode component and a cathode component. The film includes a vinyl alcohol copolymer with functional comonomer units such as sulfonic acid functionalized units or salts thereof. The films are desirable for use in battery separators because they exhibit superior resistance to degeneration by oxidation, enabling the manufacture of batteries with improved conductivity, longer discharge times, and longer cycle lives. | 06-11-2009 |
| 20090325058 | ELECTROCHEMICAL DEVICE AND METHOD FOR PRODUCTION THEREOF - An electrochemical device of the present invention includes a positive electrode, a negative electrode, a non-aqueous electrolyte, and a separator. The separator includes a first porous layer composed mainly of a thermoplastic resin and a second porous layer composed mainly of insulating particles with a heat-resistant temperature of 150° C. or higher. The first porous layer is disposed to face the negative electrode. | 12-31-2009 |
| 20080261106 | ELECTRICITY ELEMENT, SEPARATOR AND MANUFACTURING METHOD THEREOF - A separator includes a separator body and a first film. The separator body is formed by mixing and solidifying a first material and a second material and then removing the first material by an alkaline liquid etching process. The separator body has a plurality of irregular holes formed corresponding to the removed first material. The first film is disposed on one side of the separator body. | 10-23-2008 |
| 20100183907 | Hard Spacers in Microporous Membrane Matrix - A battery separator may be formed with hard spacers made from ceramic and other high temperature materials. The spacers may be incorporated into a microporous membrane so that the microporous matrix may capture and hold the spacers. The spacers may be solid or hollow glass beads that are in the range of 30% to 100% of the thickness of the separator, and may comprise less than 10 weight percent. The resulting membrane may be largely microporous, and the separators may help battery electrodes to remain physically separated, even after internal temperatures exceed the melt temperature of the separator. | 07-22-2010 |
| 20090148759 | ENERGY STORAGE DEVICE CELL AND CONTROL METHOD THEREOF - An energy storage device cell includes: a capacitor cathode including a capacitor cathode collector foil, and a capacitor cathode electrode layer formed on one face of the capacitor cathode collector foil and containing microparticles of activated carbon; a first separator; a common anode including an anode collector foil having a through-hole, and an anode electrode layer formed on one face of the anode collector foil; a second separator; and a battery cathode including a battery cathode collector foil, and a battery cathode electrode layer formed on one face of the battery cathode collector foil and containing particles of a lithium-containing metal compound. The first separator is sandwiched by the capacitor cathode electrode layer and the anode electrode layer. The second separator is sandwiched by the anode collector foil and the battery cathode electrode layer. | 06-11-2009 |
| 20080274399 | Secondary battery - A secondary battery includes: a positive electrode; a negative electrode; a porous electron-insulating layer adhered to a surface of at least one selected from the group consisting of the positive electrode and the negative electrode; and an electrolyte. The porous electron-insulating layer comprises a particulate filler and a resin binder, and the particulate filler comprises an indefinite-shape particle comprising a plurality of primary particles that are joined to one another. A neck is preferably formed between the primary particles. Since the porous electron-insulating layer has high porosity, it is possible to obtain a secondary battery that exhibits excellent low-temperature characteristics, which are particularly important in actual use, and that is capable of discharging at a large current. | 11-06-2008 |
| 20090214944 | High Capacity Electrodes - A high capacity electrode includes a conducting substrate on which a plurality of support filaments are disposed. Each of the support filaments have a length substantially greater than their width and may include, for example, a carbon nano-tube (CNT), a carbon nano-fiber (CNF), and/or a nano-wire (NW). The support filaments are coated with a material, such as silicon, having a greater ion absorbing capacity greater than the neat support filaments. A trunk region of the support filaments proximate to the substrate is optionally kept free of ion absorbing material. This trunk region allows for the expansion of the ion absorbing material without detaching the support filaments form the substrate. | 08-27-2009 |
| 20110256441 | SEPARATOR FOR BATTERY - Disclosed are a separator for a battery and a battery. The separator includes a porous film, a first roller, and a second roller. The first and second rollers are associated with both ends of a porous film. The first roller is wound with a portion of the porous film and is configured to rotate to unroll the film. The second roller is configured to rotate in an opposite direction to a rotary direction of the first roller to roll up the film. | 10-20-2011 |
| 20120164510 | CERAMIC-METAL SEALING STRUCTURE, AND ASSOCIATED METHOD - A method of sealing a ceramic component to a metal component for a metal halide battery is provided. The method involves the steps of coating a portion of the ceramic component with a metallic coating, and then bonding the coated ceramic component to the metal component. The metallic coating includes a reactive metal. A sealing structure formed by using such a method is also presented. | 06-28-2012 |
| 20080199769 | Valve-regulated lead-acid battery and production method thereof - To improve the penetration short-circuit resistance of a valve-regulated lead-acid battery. A mixed and scooped mat of glass fibers and organic fibers is used as a separator | 08-21-2008 |
