Abstract: A rechargeable battery includes an electrode assembly, a can, a cap plate, and a heat dissipating portion. The electrode assembly includes a first electrode, a separator, and a second electrode. The can accommodates the electrode assembly in an internal space. The cap plate is coupled to an open end of the can to close the can, and the cap plate is provided with a notch groove and at least one opening positioned at a distance from the notch groove. The heat dissipating portion at least partially fills the opening.

Abstract: A rechargeable battery includes an electrode assembly, a can accommodating the electrode assembly inside and including a terminal hole, a rivet terminal including a pillar part extending into the terminal hole and a head part coupled to the pillar part, and an insulator between the rivet terminal and the can. The insulator includes a middle part that surrounds the pillar part and extends into the terminal hole, an outer part contacting the head part and the outer surface of the can, and an inner part contacting the inner surface of the can. At least two of the middle part, the outer part, and the inner part include different insulating materials with different heat resistance temperatures.

Abstract: An electrode assembly includes: a first electrode having a first coated portion and a first uncoated portion at an edge of the first coated portion; a second electrode having a second coated portion and a second uncoated portion at an edge of the second coated portion; a separator between the first electrode and the second electrode; a first insulating layer on one surface of the first uncoated portion; and a second insulating layer on another surface of the first uncoated portion. Lengths of the first insulating layer and the second insulating layer are different from each other.

Abstract: An offshore facility for producing a liquefied natural gas using an associated gas includes a crude oil production offshore facility having a crude oil processing device for refining crude oil collected from a subsea well to produce oil, and a gas reinjection device for compressing an associated gas separated in crude oil refining process to be reinjected into a reservoir, and a liquefied natural gas production offshore facility supplied with a feed gas including at least a part of the associated gas from the crude oil production offshore facility, and processing and liquefying the feed gas to generate a liquefied natural gas. The crude oil production offshore facility includes a feed gas supply unit for recovering a back-flow gas formed when an injection gas compressed by the gas reinjection device flows backward and generating the feed gas by using the back-flow gas.

Abstract: Disclosed herein is a cylindrical secondary battery constructed in a structure in which a crimping region, at which a cap assembly is mounted to the open upper end of a cylindrical container having an electrode assembly mounted therein, is formed at the upper end of the container, wherein the crimping region is constructed in a structure in which the upper end of the crimping region is gently bent at a predetermined radius of curvature (R), such that the crimping region surrounds a gasket located at the inside of the crimping region, the bent front end extends inward, such that the bent end presses the gasket, and an inclination of a predetermined angle is formed at the sidewall of the crimping region, such that the upper part of the crimping region is directed inward. According to the secondary battery of the present invention, the sealability of the gasket is improved, and external impacts are partially absorbed by the inclination formed at the crimping region.
