Abstract: A composite cathode active material, a method of preparing the composite cathode active material, a cathode including the composite cathode active material, and an all-solid secondary battery, are provided. The composite cathode active material may include a core including a lithium-containing sulfide-based cathode active material; and a shell conforming to a surface of the core, where the shell may include at least one first metal oxide represented by formula MaOb (0<a?3 and 0<b<4, wherein if a is 1, 2, or 3, b is not an integer); and a carbonaceous material, the first metal oxide may be disposed within a matrix of the carbonaceous material, and M may be at least one metal selected from among Groups 2 to 16 in the Periodic Table of Elements.

Abstract: An all-solid secondary battery includes a positive electrode layer, a negative electrode layer, and a solid electrolyte layer between the positive electrode layer and the negative electrode layer, wherein the positive electrode layer includes a positive electrode current collector and a positive electrode active material layer, the positive electrode active material layer includes a lithium-containing sulfide-based positive electrode active material, the lithium-containing sulfide-based positive electrode active material includes Li2S, a Li2S-containing composite, or a combination thereof, the all-solid secondary battery includes a first inactive member on one surface of the positive electrode layer, the negative electrode layer includes a negative electrode current collector and a first negative electrode active material layer, a ratio of initial charge capacity of the first negative electrode active material layer to initial charge capacity of the positive electrode active material layer is in a range of ab

Abstract: A method for removing an icon in a mobile terminal is presented. The method includes, displaying an icon display area and a menu area on a display screen of the mobile terminal, wherein the icon is displayed in the icon display area and a predetermined executing icon menu is displayed in the menu area, selecting the icon, modifying the menu displayed in the menu area to a removing menu when a preliminary removing signal is input on the selected icon, and removing the selected icon in response to the movement of the selected icon to a predetermined area of the removing area.
