Abstract: A power supply protective device, when obtaining an open voltage when a second switch is brought into a closed state and a first switch is brought into an open state during discharging of a power supply, and obtaining a close voltage when the second switch is brought into the closed state and the first switch is brought into the closed state during discharging of the power supply, diagnoses the first switch as having a failure or not on the basis of the open voltage and the close voltage. When executing first a close instruction to the first switch and the second switch, if a voltage difference is less than a first threshold voltage, the first switch is determined to have no open failure, and/or when not less than a second threshold voltage, the second switch is determined to have no open failure.

Abstract: Provided is an electrode assembly including: a negative electrode including a negative electrode current collector (NC) and a negative electrode active material layer (NAL) disposed on at least one surface of the NC; a positive electrode including a positive electrode current collector (PC), a positive electrode active material layer (PAL) disposed on at least one surface of the PC, and an undercoat layer being disposed between the PC and the PAL and being higher in resistance value than the PC. The negative electrode and the positive electrode are stacked on each other. In at least one side of the thus stacked negative and positive electrodes, the NAL projects from an edge of the PAL in a direction in which the NC and PC extend, and the undercoat layer projects from an edge of the NAL in the direction.
