Abstract: A battery disposal container and a battery disposal device are disclosed. A battery disposal container includes a housing configured to accommodate a battery, and including a first opening through which a fluid is configured to flow; and an insulating member arranged in the housing and facing an inner surface of the housing, and including a second opening communicating with the first opening.

Abstract: An electrode assembly includes a separator, and a first electrode and a second electrode positioned across the separator. The separator, the first electrode, and the second electrode are wound around two winding axes and then implement a shape including a central portion and a pair of rounded portions positioned at both sides (e.g., opposite sides) of the central portion. The first electrode includes a first substrate having an inner end, a first composite material layer positioned on a part of the first substrate at a distance from the inner end, and a protection layer positioned on the inner surface of a bent part of the first substrate at a distance from the inner end and the first composite material layer.

Abstract: Disclosed is a secondary battery that reduces or prevents heat transfer from a battery cell to surroundings thereof if an event occurs in the battery cell. The secondary battery includes an electrode assembly including a first electrode plate and a second electrode plate including an electrode uncoated portion protruding from one side, a case for receiving the electrode assembly, and defining a lower opening at a lower end, a cap assembly at one surface of the case for sealing the case, and including an electrode terminal electrically connected to the electrode uncoated portion, and a sealing plate coupled along a perimeter of the case at the lower opening.

Abstract: A battery pack configured to suppress a fire by spraying a coolant from above or submerging at least a portion of the battery pack in the coolant in response to a fire occurring in the battery pack. In response to a fire occurring in a battery pack, a coolant may be sprayed from above to serve as a sprinkler. The fire may be extinguished and heat propagation may be suppressed by submerging at least a portion of the battery pack in the coolant. Since the fire may be extinguished immediately and the heat propagation may be prevented even when a battery cell reaches thermal runaway, safety of the battery pack may be improved.

Abstract: A rechargeable battery module incudes a plurality of battery cells stacked in a first direction; a bus bar holder including a bottom part covering the battery cells and exposing electrode terminals of the battery cells; a bus bar connecting the electrode terminals; and a temperature sensor arranged on an electrode terminal of the electrode terminals to detect a temperature of a battery cell of the battery cells, the temperature sensor including a first sensing part to transmit a detection signal through a body part connected to the first sensing part, the bus bar holder further including a vent pipe part connected to the bottom part to define a vent passage toward a vent of the battery cells along the first direction, and the temperature sensor further including a second sensing part connected to the body part, extending through the vent pipe part, and exposed to the vent passage.

Lubricant additives that includes the alkylthioperoxydiphosphates.

Abstract: A plasma display panel enhancing an emission efficiency of a green phosphor layer by increasing an excitation efficiency of a green phosphor layer using visible light emitted from a dielectric layer or barrier ribs, the plasma display panel including a first substrate and a second substrate disposed to face the first substrate. A plurality of display electrodes are formed on the first substrate. A first dielectric layer is formed on the first substrate to cover the display electrodes. A plurality of address electrodes are formed on the second substrate in a direction crossing the display electrodes. A second dielectric layer is formed on the second substrate to cover the address electrodes. Barrier ribs are disposed in a space between the first dielectric layer and the second dielectric layer to form a plurality of discharge cells. The second dielectric layer and the barrier ribs comprise a short wavelength phosphor material.
