Abstract: An injector inlet structure for injecting an electrolyte solution to a battery cell includes a closed-loop shaped outer ring configured to define an inner region; a momentum reduction portion disposed at a center portion of the inner region, spaced apart from the outer ring, to collide with electrolyte solution injected to the center portion of the inner region among the electrolyte solution injected through the inner region; and at least one connection member extending from the outer ring toward a center of the outer ring to be connected to the momentum reduction portion.

Abstract: The present application can provide a curable composition capable of securing processability due to excellent blending properties with a filler while having little viscosity change with time and for forming a cured product having excellent electrical insulation performance, and can provide a device comprising, between an exothermic element and a cooling region, a cured product of a tow-component curable composition including the curable composition in thermal contact with both.

Abstract: A jelly roll includes an electrode assembly made by winding a stack of a first electrode, a separator, and a second electrode, and an insulation tape configured to cover at least a part of a lateral surface of the electrode assembly and at least a part of an end of the electrode assembly, in which the insulation tape has at least one notching pattern provided in a region that covers at least a part of the end of the electrode assembly. The jelly roll can be used in a secondary battery, a battery module, and a battery pack.

Abstract: A secondary battery includes a wound electrode assembly having a first electrode, a separator, and a second electrode, and a battery can configured to accommodate the electrode assembly, the battery can having a partially closed portion at one side thereof, an open portion at the other side opposite to the partially closed portion, and a cylindrical sidewall, the electrode assembly having a first end from which a first electrode tab is extended, and a second end from which a second electrode tab is extended, the first end and the battery can being electrically connected, the sidewall of the battery can having an insulative coating layer provided on an inner surface corresponding to the second end. A second current collecting plate is electrically connected to the second electrode tab. An insulation member is provided between the second current collecting plate and the bottom portion of the battery can.
