Abstract: The secondary battery according to the present invention has a vent deformation accelerator which promotes the operation of a vent formed on a wide side of a can in the cap plate, a bottom side of a can or a narrow side of a can so that the vent operates at the low pressure. Therefore, a secondary battery is provided with a vent which operates at a lower pressure than the operating pressure of existing vents. Also, the vent can be formed relatively thick when the operating vent which operates at the same pressure as the operating pressure of an existing vent so that it can avoid forming a vent having a minute thickness, thereby reducing the manufacturing costs and processing time.

Abstract: Provided are a supported metallocene catalyst which has excellent supporting efficiency due to an interaction between a cocatalyst supported on a carrier and a metallocene compound substituted with a functional group that can function as a Lewis base, such as acetal, ketal, tert-alkoxy alkyl, benzyloxy alkyl, substituted benzyloxy alkyl, monothioacetal, or monothioketal, and a method of polymerizing an olefin using the supported metallocene catalyst. In the supported metallocene catalyst, the metallocene catalyst is strongly bound to the carrier due to a Lewis acid-base interaction between the metallocene compound and the cocatalyst, and thus the metallocene catalyst is not separated from the carrier during the polymerization of polyolefin in a slurry or gas phase method. Thus, fouling is prevented and the prepared polymer has a good particle shape and a high apparent density. Thus, the supported metallocene catalyst can be suitably used in a conventional slurry or gas phase polymerization process.

Abstract: A prismatic can type lithium ion rechargeable battery of the present invention includes an electrode assembly, a prismatic can accommodating the electrode assembly, a cap assembly including a cap plate closing an upper opening portion of the prismatic can. A distortion prevention portion is formed on a side surface of the prismatic can. A safety vent is formed on a side surface of the prismatic can, and includes a weakened portion. The weakened portion is formed outside a periphery of the distortion prevention portion. Accordingly, if can distortion of the prismatic battery is caused by the internal pressure, force acting on the safety vent is concentrated on the weakened portion, breaking the weakened portion. Therefore, the safety vent of the present invention prevents the explosion of the battery or the firing, and improves the safety and reliability of the prismatic can type lithium ion rechargeable battery.

Abstract: An isolation method for a single crystalline silicon microstructure using a triple layer structure is disclosed. The method includes forming the triple layer composed of an insulation layer formed over an exposed surface of the silicon microstructure, a conductive layer formed over the entire insulation layer, and a metal layer formed over a top portion of the microstructure; and partially etching the conductive layer to form electrical isolation between parts of the microstructure. The method does not require a separate photolithography process for isolation, and can be effectively applied to microstructures having high aspect ratios and narrow trenches. Also disclosed are single crystalline silicon microstructures having a triple layer isolation structure formed using the disclosed method.
