Abstract: A button-type secondary battery includes a lower can having a bottom surface; an upper can having a top, the upper can and the lower can being coupled to define a space therein; an electrolyte in the space; an electrode assembly in the space and including a negative electrode, a separator, and a positive electrode wound together; a gasket between the upper can and the lower can to electrically insulate the upper and lower cans; a top insulator that is electrically insulating and covering a top surface of the electrode assembly; and a bottom insulator that is electrically insulating and covering a bottom surface of the electrode assembly. The top and bottom insulators are each configured to expand in volume by absorbing the electrolyte. Surfaces of at least one of the top insulator and the bottom insulator are coated with a protective layer to prevent thermal shrinkage from occurring.

Abstract: Disclosed herein relates to a positive electrode for a lithium secondary battery, wherein the positive electrode not only has an excellent energy density by containing a ternary compound containing nickel (Ni), cobalt (Co), manganese (Mn), etc. as a positive electrode active material, but also has an advantage of improving safety due to internal short circuit of a secondary battery by including an iron phosphate compound in the outermost part with respect to a positive electrode current collector.

Abstract: A button type secondary battery includes a wound electrode assembly; a lower can with the electrode assembly and an electrolyte in the lower can; a top plate to close the lower can; a positive electrode terminal coupled to the top plate through a gasket to be electrically insulated from the top plate with a portion of the positive electrode terminal passing through a hole in the top plate to be bonded to a positive electrode tab; a top insulator covering a top surface of the electrode assembly; and a bottom insulator covering a bottom surface of the electrode assembly. The top insulator and the bottom insulator are each configured to expand in volume by absorbing the electrolyte. Surfaces of at least one or more of the top insulator and the bottom insulator are coated with a protective layer configured to prevent thermal shrinkage from occurring.

Abstract: The present invention relates to a method, system, and computer-readable recoding medium for sharing a result related to contents. The method for sharing a result related to contents includes the steps of assigning different identifications (IDs) to communities in which the contents are primarily and/or secondarily posted if a user requests to directly scrap and post the contents of a server, and collectively providing a result created in relation to the contents belonging to communities having a common ID if the result is created in relation to the primarily and/or secondarily posted contents.

Abstract: An input device includes a scroll unit installed on a case and configured to select a menu, a manipulation unit configured to operate a menu selected by the scroll unit and having a translucent region, and a menu display unit mounted on a rear surface of the manipulation unit and configured to display the menu selected by the scroll unit through the translucent region.

Abstract: A mobile communication terminal is provided that includes a terminal body and a camera assembly mounted in the terminal body, wherein the camera assembly includes a camera, a driving unit for generating driving power for rotating the camera, and a housing assembled as one body at the terminal body by rotatably supporting the camera and fixing the driving unit. The camera and the driving unit can be stably supported within the housing and can be easily mounted therein.

Abstract: A sound guide for a speaker is capable of guiding a sound of a desired volume to a desired position regardless of installation structure of the speaker. The sound guide for a speaker includes a speaker support for supporting the speaker in a case, and a sound guide groove formed in an inner side of the speaker support, for guiding the direction of the audible signal of the speaker at a predetermined angle. The sound propagation groove has one side coupled with the speaker and other side coupled with a sound propagation hole which is formed in the case. A handset for mobile communication using the sound guide includes a case having a speaker therein, and a sound propagation hole for propagating the audible signal generated by the speaker to outside, wherein the speaker is slanted at a predetermined angle with respect to a front side of the case.
