Abstract: An organic electric element according to an embodiment of the present disclosure includes a first electrode, a second electrode, and an organic material layer formed between the first electrode and the second electrode. The organic material layer may include a plurality of light-emitting auxiliary layers and the LUMO/HOMO energy levels of the plurality of light-emitting auxiliary layers are limited to specific conditions in relation to the neighboring organic material layers, thereby the driving voltage, the luminous efficiency and the lifetime of the organic electric element can be improved.

Abstract: An embodiment integrated operating apparatus for different types of gates includes a driving motor, a main shaft rotatable by the driving motor, a first clutch portion at a first side of the main shaft and configured to selectively transmit power to a first gate of a vehicle, the first clutch portion including a first clutch and a first gear selectively engaged with each other, and a second clutch portion at a second side of the main shaft and configured to selectively transmit power to a second gate of the vehicle, the second clutch portion including a second clutch and a second gear selectively engaged with each other, wherein the first and second gates are configured to be independently operated based on the first clutch portion being in an engaged state or a released state and the second clutch portion being in the engaged state or the released state.

Abstract: Cathodes and lithium secondary batteries including the cathodes are disclosed. In some implementations, a cathode may include a cathode current collector and a cathode active material layer disposed on the cathode current collector and including cathode active material particles such that the cathode active material layer satisfies a specific equation. The cathode active material particles may include lithium metal oxide particles that include nickel, and may have a mole fraction of cobalt of 0.02 or less with respect to all elements except for lithium and oxygen.

Abstract: A gas detection device comprises a pump module for drawing in air; a sensor module including a plurality of unit sensors detecting a gas included in the air; a driving module driving the pump module and the sensor module; and a case including a main body mounted to allow at least one among the pump module, the sensor module, and the driving module to be detachable and a cover connected to the main body to allow the at least one among the pump module, the sensor module, and the driving module to be exposed.

Abstract: A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer formed on the cathode current collector. The cathode active material layer includes cathode active material particles. The cathode active material particles include a lithium metal oxide particle containing nickel and having a mole fraction of cobalt of 0.02 or less among all elements except lithium and oxygen.

Abstract: A cylindrical secondary battery, a battery pack, and a vehicle are provided. The cylindrical secondary battery includes an electrode assembly having a first electrode tab at a first end of the electrode assembly a battery can configured to accommodate the electrode assembly through an opening portion formed at one side of the battery can, a current collecting plate including three or more tab coupling portions electrically connected to the first electrode tab, and a can coupling portion extending from ends of the tab coupling portions toward the opening portion of the battery can and having a continuous outer peripheral surface electrically connected to an inner surface of the battery can, and a top cap configured to cover the opening portion of the battery can.

Abstract: The laser welding system including a welding frame for receiving a first steel plate to be welded thereupon, at least one first clamping member to be installed above the welding frame, for fixing the first steel plate received on the welding frame, at least one second clamping member for fixing a second steel plate to be welded in close vicinity to a position at which the first steel plate is to be engaged with and welded with the second steel plate, an anvil on which the second steel plate is received, for moving the second steel plate to the position at which the first steel plate is to be engaged with and welded with the second steel plate, and a laser welding head for welding the first and second steel plates at the position at which the first steel plate is to be welded with the second steel plate. The first and second clamping members and anvil are operated by air bags.
