Abstract: A lithium secondary battery includes positive and negative electrodes, and a nonaqueous electrolyte having lithium-ion conductivity. In the lithium secondary battery, lithium metal deposits on the negative electrode during charging, and the lithium metal dissolves from the negative electrode during discharging. The nonaqueous electrolyte contains a lithium salt, and a solvent. The solvent includes a first solvent: a chain ether containing no fluorine element, a second solvent: a chain fluorinated ether having a fluorination rate of 60% or more, and a third solvent: a fluorinated ether having a fluorination rate of more than 0% and less than 60%. When the number of moles of the first solvent contained in the nonaqueous electrolyte is M1, and the number of moles of the third solvent contained in the nonaqueous electrolyte is M3, a molar ratio M1/M3 is 0.25 or more and less than 3.

Abstract: A shutter speed determination device includes a motion detector and controller. The motion detector, on a block-by-block basis having a specified block size, performs detection processing of a motion vector for image data obtained by capturing a subject image. The controller, while reducing the block size, causes the motion detector to execute the detection processing repeatedly, each time executing the detection processing the controller finds a motion vector related value that changes in a same direction as a direction in which a magnitude of the motion vector changes, the controller determines a shutter speed used when capturing the subject image thereafter, based on the motion vector related value found.

Abstract: An electrode group includes a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and a positive electrode lead electrically connected to the positive electrode. The positive electrode includes a positive electrode current collector and a positive electrode active material layer carried on each main surface of the positive electrode current collector. The positive electrode current collector has an exposed section that does not carry the positive electrode active material layer. The negative electrode includes a negative electrode current collector and a negative electrode active material layer carried on each main surface of the negative electrode current collector and has a first region and a second region. The mass of the negative electrode active material layer in the first region per unit area is smaller than the mass of the negative electrode active material layer in the second region per unit area.

Abstract: An arc detection device includes an obtainer and a determiner. The obtainer obtains a measurement result for a voltage applied to one target power supply line among a plurality of power supply lines to which power is supplied from a DC power source. The determiner determines, based on a component of a specific frequency band in the measurement result for the voltage obtained by the obtainer, whether there is a possibility of an arc fault occurring in the plurality of power supply lines.
