Abstract: A vehicular power supply device to be equipped in a vehicle includes an electric storage unit group, an inverter, a driving motor, a converter, an electric device group, a first switch, and a second switch. The electric storage unit group includes first and second electric storage units. The driving motor is to be coupled to the electric storage unit group via the inverter. The electric device group is to be coupled to the electric storage unit group via the converter. The first switch is to be controlled between a state where the first electric storage unit is coupled to the inverter and a state where the first electric storage unit is coupled to the converter. The second switch is to be controlled between a state where the second electric storage unit is coupled to the inverter and a state where the second electric storage unit is coupled to the converter.

Abstract: The present disclosure relates to a method for manufacturing the laminated film that is BSPC (Back Side Printable Clear) and has excellent interlayer adhesion. The method involves a first UV curing step and a second UV curing step and the laminated film includes a transparent film layer, a UV curable ink layer, and an adhesive layer. The first UV curing step includes disposing the UV curable ink layer on the transparent film layer and partially curing the UV curable ink layer by performing a first UV irradiation. The second UV curing step includes disposing the adhesive layer on a surface of the UV curable ink layer opposite the transparent film layer, and further curing the UV curable ink layer by performing a second UV irradiation.

Abstract: To provide an electrolytic copper foil for a negative electrode for a lithium-ion secondary battery with which it is possible to produce a long-life lithium-ion secondary battery in which there is no decline in the capacity retention ratio even when the charge-discharge cycling is repeated, that has long life, and no deformation of a negative electrode current collector occurs. The electrolytic copper foil constituting the negative electrode current collector for the lithium-ion secondary battery has, after heat treatment at from 200 to 400° C., a 0.2% proof stress of 250 N/mm2 or more, and elongation of 2.5% or more; and the surface on which an active material layer of the electrolytic copper foil is provided has been rust-proofed, or roughened and rust-proofed.
