Abstract: A lithium secondary battery which includes an electrode assembly in which a positive electrode plate, a negative electrode plate, and a separator interposed between the positive electrode plate and the negative electrode plate are wound in one direction, a battery can in which the electrode assembly is accommodated, and a sealing body which seals an open end of the battery can. The positive electrode plate includes a positive electrode active material layer that includes a positive electrode active material, a conductive material, and a binder. The positive electrode active material may include a lithium nickel-containing oxide that has at least one of single particles or quasi-single particles, and the conductive material includes a combination of single-walled carbon nanotubes and bundle-type carbon nanotubes.

Abstract: The present invention relates to a mobile phone slide module, and more particularly to a mobile phone slide module in which scratches and noise do not occur during the sliding operation of a mobile phone. The mobile phone slide module according to the present invention is installed between a movable plate fixed to an upper body where a display unit is installed and the fixed plate fixed to a lower body where a keypad is mounted, and provides elasticity when the movable plate slides on the fixed plate.

Abstract: A side key module installed at a side of a mobile communication terminal, contactly coupled up to a PCB embedded in the terminal, and simply fabricated without a soldering process. The side key module disposed between a side key installed at the side of the terminal, and the PCB installed in the terminal, including: a first plate of conductivity configured in a lengthwise form including a cut-out space and contacting with the PCB; a second plate of conductivity configured in the same plane with the first plate and disposed in the cut-out space of the first plate, contacting with the PCB; a body accommodating the first and second plates; and a metal dome joining with a side of the body and enabling the first and second plates to be electrically connected together by contacting with the first and second plates if the side key is pressed.

Abstract: A side key module for a mobile communication terminal is provided between side keys mounted on a side surface of the mobile communication terminal and an internal printed circuit board. The side key module includes a PCB which is in the shape of an elongated plate and on which a conductive material pattern is formed, a contact terminal having one side which is in contact with the pattern and the other side which is in contact with the internal printed circuit board, and a metal dome which is coupled to one side of the PCB and is in contact with the pattern to electrically connect the pattern to the contact terminal when the side key is pressed.

Abstract: Disclosed is a side key module installed at a side of a mobile communication terminal, contactly coupled up to a PCB embedded in the mobile communication terminal, and simply fabricated without a soldering process. The side key module is disposed between a side key, which is installed at the side of the mobile communication terminal, and the PCB installed in the mobile communication terminal, including: a first plate of conductivity configured in a lengthwise form including a cut-out space and contacting with the PCB; a second plate of conductivity configured in the same plane with the first plate and disposed in the cut-out space of the first plate, contacting with the PCB; a body accommodating the first and second plates; and a metal dome joining with a side of the body and enabling the first and second plates to be electrically connected together by contacting with the first and second plates if the side key is pressed.

Abstract: Disclosed is a multi-step pressurized switch providing various signals in response to variation of pressure applied thereto. The multi-step pressurized switch includes a switched PCB connected to a PCB of an electronic device and having at least one or more contact points on the top, and an elastic plate settled on the top of the switched PCB and electrically connecting the contact points with each other if there is pressure. The elastic plate includes a first projection protruding upward from the edge of the elastic plate, a second projection joining with the first projection and protruding in the same direction with the first projection, and a first slope bending down toward a direction opposite to the first projection from the edge of the elastic plate.

Abstract: The slide hinge module for a mobile phone with a built-in keypad is disclosed, which is used in a portable terminal including a first body having a keypad, and a second body which slides and be opened or closed in a left or right direction when viewing from a front side of the first body and has a display screen part on its front side, comprises a moving plate which is fixedly engaged to the first body; a fixing plate of which a front side is fixedly engaged to the second body, and a backside is flat on the same plane, and which slides in left and right directions along with the moving plate; and an elastic apparatus which provides an elastic force so that the moving plate can stay in a left or right side of the fixing plate.

Abstract: The slide hinge module for a mobile phone is provided, which comprises a fixing plate which is fixed in the body; a moving plate which is fixed in the cover; a guide rail which is provided in one side of the moving plate in a horizontal direction; a slide member which is engaged while corresponding to the guide rail and reciprocates along the guide rail and is fixed in one side of the fixing plate; and an elastic assembly which is installed in one side of the guide rail and slides the moving plate with respect to the fixing plate, whereby a concave part is formed in one side of the guide rail, and said elastic assembly is installed in the concave part.

Abstract: The present invention relates to an apparatus for opening and closing a cover of a cellular phone in which a slide module capable of slidably opening and closing a cover of a cellular phone is constructed in a structure of using an elastic force of a spring, so that it is possible to precisely recognize an opening and closing operation of a cover, and an opening and closing operation of a cover is efficiently achieved.
