Abstract: An electrode assembly and a secondary battery using the same, the electrode assembly including: first and second electrode plates, which are wound with a separator disposed therebetween; and first and second electrode tabs respectively adhered to the first and second electrode plates. The first electrode plate extends from a bottom surface of the electrode assembly, has a groove, and is bent at the groove. The secondary battery includes: the electrode assembly; a can to house the electrode assembly; and a cap assembly to seal the can. The first electrode tab is connected to the bottom of the can.

Abstract: Disclosed is a vacuum pump for vehicles which reduces noise of exhaust air generated during operation of the vacuum pump.

Abstract: A phase change memory device and a method of manufacturing the phase change memory device are provided. The phase change memory device may include a switching element and a storage node connected to the switching element, wherein the storage node includes a bottom electrode and a top electrode, a phase change layer interposed between the bottom electrode and the top electrode, and a titanium-tellurium (Ti—Te)-based diffusion barrier layer interposed between the top electrode and the phase change layer. The Ti—Te based diffusion barrier layer may be a TixTe1?x layer wherein x may be greater than 0 and less than 0.5.

Abstract: A secondary battery includes an electrode assembly having a first electrode plate electrically connected to a first electrode tab and a second electrode plate electrically connected to a second electrode tab and an outer casing housing the electrode assembly. At least one of the first electrode tab or the second electrode tab includes at least one first groove extending in a longitudinal direction.

Abstract: An electrode assembly comprises a positive electrode plate having a positive electrode collector and a positive electrode coating portion formed one the positive electrode collector, a negative electrode plate having a negative electrode collector and a negative electrode coating portion formed on the negative electrode collector; and a separator. Either the positive electrode coating portion or the negative electrode coating portion is divided into a coating-starting portion, a coating-finishing portion and a uniform region between the coating-starting portion and the coating-finishing portion.

Abstract: In method for freeze-crushing waste resources, freezing gas is first created by collecting freezing heat source of liquefied petroleum gas during a heat exchange process between the liquefied petroleum gas and cooling gas, and then the waste resources stored in a freezing tank is frozen to a temperature where the waste resources can be easily crushed by supplying the freezing gas to the freezing tank. Next, the frozen waste resources is crushed in an crushing apparatus, after which the freezing gas is separated from the crushed waste resources in a separate apparatus and the freezing gas for is collected the purpose of reuse.
