    Abstract: Disclosed is an electrolytic capacitor including: an electrode foil; and a lead member that is connected to the electrode foil. The lead member includes a lead wire and a plate-shaped tab portion that is provided at one end portion of the lead wire. The tab portion has a surface with an arithmetic average roughness Ra of 4 μm or more. The electrode foil and the lead member are connected by a crimping portion in an overlapping portion in which the tab portion and the electrode foil overlap each other when the electrode foil is placed on the surface of the tab portion.

    Abstract: A contact tip for welding includes: a tip case; a power supply tip that is housed in the tip case and supplies power to a welding wire supplied from a side close to one end of the power supply tip while holding the welding wire at another end opposite to the one end; and a guide that presses the power supply tip from the side close to the one end and houses the power supply tip in the tip case, in which the power supply tip has a shape in which an outer diameter from a press point pressed by the guide to a fulcrum in contact with the tip case increases from the press point toward the fulcrum, and the power supply tip is rotated about the fulcrum by pressing of the guide to hold the welding wire at the other end.

    Abstract: An image display device according to an embodiment includes: a display panel which displays an image on a front surface of the display panel; an antenna unit which is positioned in front of the front surface of the display panel; and a front wall which accommodates the antenna unit. For example, the antenna unit overlaps the display panel in a front-back direction. For example, the front wall is disposed along a lower edge of the display panel, and protrudes forward relative to the display panel.

    Abstract: A charger information holding unit of a management system holds an identification information item and charging efficiencies of a plurality of chargers for charging an electric vehicle, the identification information item and the charging efficiencies being associated with each other. A communication unit of the management system receives an identification information item on a charger from an electric vehicle connected to the charger, via a network. A creating unit of the management system creates a charging plan for the electric vehicle, based on a required charging amount and a target charging termination time. The creating unit of the management system refers to the charger information holding unit and determines a charging efficiency of the charger connected to the electric vehicle, based on the received identification information item, and creates a charging plan with the charging efficiency of the charger. The communication unit of the management system transmits the created charging plan to the electric vehicle via the network.

    Abstract: A lithium secondary battery includes: a wound electrode group including a positive electrode, a negative electrode including a negative electrode current collector, and a separator disposed between the positive electrode and the negative electrode; a core member disposed in a hollow part of the electrode group; and a non-aqueous electrolyte having lithium ion conductivity. Lithium metal is deposited on the negative electrode when the battery is charged, and the lithium metal dissolves when the battery is discharged. The negative electrode current collector is an austenitic stainless steel foil or an oxygen-free copper foil.

    Abstract: Disclosed is a non-aqueous electrolyte secondary battery including: a negative electrode that includes a negative electrode active material; a separator; a positive electrode that is provided to oppose the negative electrode with the separator interposed therebetween; and a non-aqueous electrolyte. The negative electrode active material includes 3 mass % or more of a silicon-containing material. The silicon-containing material includes carbon composite particles. Each of the carbon composite particles includes a carbon phase and a silicon phase dispersed in the carbon phase. The non-aqueous electrolyte contains a 5- or 6-membered sulfur-containing cyclic ester compound that has a carbon-carbon unsaturated bond and a structure represented by —O—S(═O)n-O—, where n is 1 or 2.
