  • Patent number: 9236196
    Abstract: The electric double-layer capacitor of the present invention comprises an electrolyte solution comprising ?-butyrolactone as the solvent and a coated electrode. The coated electrode is produced by using water as the solvent, and prepared by coating a slurry onto a current collector, wherein the slurry consists of an electrode material which is the solute, an electrically conductive auxiliary agent, and an elastomer having an expansion rate of 50% or less in ?-butyrolactone at 85° C. after 100 hours as the binding agent. For example, a styrene-butadiene elastomer is employed as the elastomer. Because expansion rate in ?-butyrolactone is low, deterioration of internal resistance does not occur. Styrene-butadiene elastomer is easy to handle since water can be used as the solvent for the slurry.

  • Publication number: 20140322607
    Abstract: A lithium-metal-oxide positive electrode having a layered or spinel structure for a non-aqueous lithium electrochemical cell and battery is disclosed comprising electrode particles that are protected at the surface from undesirable effects, such as electrolyte oxidation, oxygen loss or dissolution by one or more lithium-metal-polyanionic compounds, such as a lithium-metal-phosphate or a lithium-metal-silicate material that can act as a solid electrolyte at or above the operating potential of the lithium-metal-oxide electrode. The surface protection significantly enhances the surface stability, rate capability and cycling stability of the lithium-metal-oxide electrodes, particularly when charged to high potentials.

  • Publication number: 20140272589
    Abstract: A negative electrode active material for an electric device according to the present invention includes crystalline metal having a structure in which a size in a perpendicular direction to a crystal slip plane is 500 nm or less. More preferably, the size in the perpendicular direction to the crystal slip plane is controlled to become 100 nm or less. As described above, a thickness in an orientation of the slip plane is controlled to become sufficiently small, and accordingly, micronization of the crystalline metal is suppressed even if breakage occurs from the slip plane taken as a starting point. Hence, a deterioration of a cycle lifetime can be prevented by applying the negative electrode active material for an electric device, which is as described above, or a negative electrode using the same, to an electric device, for example, such as a lithium ion secondary battery.
