Abstract:
Provided is a lid body including: a terminal member being mainly made up of a first metal; a sealing plate mainly made up of a second metal; and a sealing material. The sealing plate has a mounting hole for attaching the terminal member. The terminal member is inserted into the mounting hole and is attached to the sealing plate in a state where the sealing material is joined to a peripheral edge portion of the mounting hole. With as αS a coefficient of linear expansion at 25° C. of the sealing material, α1 as a coefficient of linear expansion at 25° C. of the first metal and α2 as a coefficient of linear expansion at 25° C. of the second metal, αL≤αS≤αH is satisfied, where αH is the higher value and αL is the lower value from among the α1 and α2.
Abstract:
A lid body includes a terminal member of at least one of a positive electrode and a negative electrode, a sealing plate including an attachment hole for attaching the terminal member, and a sealing material containing a thermoplastic resin and an inorganic filler. The terminal member is inserted into the attachment hole and attached to the sealing plate in a state in which the sealing material is joined to a peripheral portion of the attachment hole. Here, as the inorganic filler, an inorganic substance having a volume change rate of 20% or less after being immersed for 7 days in a test electrolyte, which is prepared at 65° C., and which contains 1200 ppm of water and 1 M of LiPF6, and moreover in which a volume ratio of a solvent thereof satisfies a relationship of ethylene carbonate:diethyl carbonate:dimethyl carbonate=1:1:1, is used.
Abstract:
A device for producing an electrode laminate includes a roller configured to press an active material layer-attached current collector layer including a current collector layer and an active material layer disposed on at least one surface of the current collector layer. A diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the roller in contact with an active material layer or a press sheet is disposed between the roller and a surface of the active material layer, and a diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the press sheet in contact with the active material layer.
Abstract:
In a vehicle body component, a bent portion that is formed in a component main body made of a metal plate is formed of a thickened portion, in which a plate thickness of the metal plate as a material of the component main body is gradually increased. Just as described, since the bent portion, on which stress is likely to be concentrated when a load is applied to the component main body, is formed of the thickened portion, a plate thickness of a portion where the stress is not concentrated can be prevented from being increased more than necessary. This can contribute to improvement of mass efficiency.
Abstract:
A lid body including: a terminal member of at least one electrode; a sealing plate having a mounting hole for attaching the terminal member; and a sealing material containing an inorganic filler. The terminal member is inserted into the mounting hole and is attached to the sealing plate in a state where the sealing material is joined to a peripheral edge portion of the mounting hole. In a microscope observation of a cross section of the sealing material, an average aspect ratio of the inorganic filler is 2 or higher, and with an average orientation angle of the inorganic filler is 30 degrees or smaller, in at least the sealing material formed on an outer surface of the sealing plate.
Abstract:
Provided is a method for producing an electrode body for an all-solid-state battery whereby cracks in the solid electrolyte layer can be suppressed even when the electrode body is pressed at a higher pressure, along with an electrode body produced by this method. The method for producing an electrode body for an all-solid-state battery disclosed herein is a method for manufacturing an electrode body for an all-solid-state battery including a solid electrolyte layer and a first active material layer bonded to a first surface of the solid electrolyte layer, including a step of superimposing the solid electrolyte layer and the first active material layer when there is a difference between the area of the solid electrolyte layer and the area of the first active material layer at the bonding surface between the solid electrolyte layer and the first active material layer, a step of providing an insulating layer in a region where it contacts the edges of the smaller of the solid electrolyte layer and the first active material layer and fills in the difference between the layers, a step of pressing the solid electrolyte layer, the first active material layer and the insulating layer in the lamination direction of the solid electrolyte layer and the first active material layer.
