  • Patent number: 11961971
    Abstract: Provided is a production method for an all-solid-state battery having a solid electrolyte layer between a positive electrode layer and a negative electrode layer, the production method including: coating or impregnating the positive electrode layer and/or the negative electrode layer with a solid electrolyte solution in which a boron hydride compound serving as the solid electrolyte has been dissolved in a solvent; and removing the solvent from the coated or impregnated solid electrolyte solution and causing the solid electrolyte to precipitate on the positive electrode layer and/or the negative electrode layer.

  • Publication number: 20240105949
    Abstract: Provided are a negative electrode binder composition which has excellent slurry stability without using a thickener, such as cellulose, in a negative electrode active material for an LIB secondary battery, and which is suppressed in the resistance to swelling by a solvent, and a negative electrode using the same and a secondary battery. A negative electrode binder composition comprising a copolymer having a hydroxyl group-containing monomer and an acid group-containing monomer as essential components, in which the copolymer has a weight average molecular weight of 700,000 or more, as measured using an aqueous GPC measurement apparatus, and in which a dried polymer film of the negative electrode binder composition has a swelling ratio of 0 to 10% by weight, as measured after immersed in a carbonate mixed solvent at 45° C. for 72 hours.

  • Patent number: 6093289
    Abstract: There is provided a highly efficient and compact ozone generating apparatus in which a very short air gap of about 0.2 mm is formed at high accuracy. Non-discharge portions are dispersed and disposed to cover an entire discharge space, or a spacer is provided to form the non-discharge portion. Further, an elastic body is mounted on a back face of an electrode, thereby enhancing an air gap accuracy of the discharge space.

  • Patent number: 4943495
    Abstract: A fuel cell in which the sealed portions formed at the peripheral edges of gas flow passages of a gas separating plate are turned so that they have a U-shaped cross section in the direction of the lamination so as to provide for elasticity. A filling member is filled in the interior of the sealed portions. This gas separating plate is used to respectively form gas flow passages through which different gas fluids are caused to flow so that they are electrochemically reacted in a pair of electrode reacting portions disposed with an electrolyte layer being interposed therebetween. In consequence, the sealed portions provided at the peripheral edges of the gas flow passages deform in accordance with the creep caused in the electrode reacting portions. This enables a balanced, adequate bearing pressure to be kept applied to the electrode reacting portions and the sealed portions, thereby enabling the fuel cell to be operated in an excellent gas sealed state for a long time.
