The aqueous electrolyte solution absorber is produced by filling a water permeable bag type member ... 08/24/06 - 20060188786 - Separator for secondary battery and porous film made of polyolefin blend and process for preparing the same It is an object of the present invention to provide a microporous film made of polyolefin blend having outstanding electrolyte wettability, puncture strength, and shut down characteristics, its manufacturing method, and a secondary battery separator. The present invention provides a microporous film and a method for manufacturing the same characterized ... 08/03/06 - 20060172199 - Liquid absorbing sheet and nonaqueous electrolyte battery pack A liquid absorbing sheet has a liquid-absorbing resin layer that can effectively absorb the nonaqueous electrolyte solution used in nonaqueous electrolyte secondary cells that make nonaqueous electrolyte battery packs (in particular, lithium ion-based nonaqueous secondary battery packs). The liquid-absorbing resin layer is obtained by irradiating a particular monomer composition with ... 06/22/06 - 20060134525 - Rechargeable lithium battery The invention relates to a rechargeable battery based on lithium metal as anode. The rechargeable lithium metal battery according to the invention comprises an electrolyte and also chlorine and fluorine containing compounds: The battery according to the invention has, in particular, a strongly improved Coulomb efficiency of the metallic lithium. ... 12/15/05 - 20050277026 - Non-aqueous secondary battery and separator used therefor A non-aqueous secondary battery separator composed of a porous film made of an organic polymer, which includes a network-like support, swells in the electrolyte solution and retains the electrolyte solution, wherein the network-like support has a mean film thickness of 10-30 μm, a basis weight of 6-20 g/m2, a Gurley ... 08/25/05 - 20050186478 - Alkaline storage battery and method for producing the same An alkaline storage battery includes: a positive electrode containing nickel hydroxide; a negative electrode; a separator layer intervening between the positive electrode and the negative electrode; and an alkaline electrolyte. The separator layer includes a water-absorbing polymer, a water repellent, an alkaline aqueous solution, and a scavenger capable of trapping ... 06/09/05 - 20050123833 - Separator for electrochemical cells A copolymer of an ethylenically unsaturated carboxylic acid, e.g. acrylic or methacrylic acid, and an aromatic sulphonate or carboxylate, e.g. sodium styrenesulphonate, either alone or supported on a substrate, may be used as a separator for an electrochemical cell such as a silver-zinc cell or a zinc-air cell. ... ### FreshPatents.com Support |
