  • Publication number: 20240380081
    Abstract: A power storage cell includes an electrode assembly, a cell case, and an external terminal. The cell case houses the electrode assembly. The external terminal is fixed to the cell case. The external terminal includes a first terminal portion and a second terminal portion. The first terminal portion is arranged above the cell case. The second terminal portion extends from the first terminal portion along the side surface of the cell case. The second terminal portion is provided with a recess. The recess is formed on a surface of the second terminal portion opposite to the other surface thereof that faces the cell case.

  • Publication number: 20240213500
    Abstract: An electrically conductive member includes a base member and a coating layer. The base member contains chromium. The coating layer covers the base member. The coating layer contains a conductive oxide and a first oxide that is an oxide of a first element whose absolute values of first ionization energy and free energy of formation of an oxide are smaller than those of chromium.

  • Publication number: 20230044104
    Abstract: A cell stack device includes at least one cell and at least one conductive member. The cell includes an element portion. The conductive member includes a base member containing chromium, a first layer containing an oxide containing zinc, and a zinc spinel portion located at the interface between the base member and the first layer. The first layer includes a first region facing the element portion. A first overlap area ratio, at which the zinc spinel portion located at a first interface between the first region and the base member overlaps with the first interface, is less than a second overlap area ratio, at which the zinc spinel portion located at a second interface between a second region where the surface of the first layer is exposed to an oxidizing atmosphere and the base member overlaps with the second interface.

  • Patent number: 10543767
    Abstract: A cushion pan for a seat cushion is formed from a metal sheet and the cushion pan includes: an outer frame section that is formed in a frame shape in a seat plan view, a pair of mutually opposing sides of the outer frame section each including a horizontal portion with a respective thickness direction along a seat up-down direction; a pair of side plate portions that extend toward one side in the seat up-down direction from facing end portions of the pair of horizontal portions; and a plate spring portion having a flat plate shape bridging between ends of the pair of side plate portions on an opposite side of the side plate portions from the pair of horizontal portions.
