Abstract: A wireless communication terminal having a function for unifying multiple messages and a method thereof are disclosed. The wireless communication terminal having a function for unifying multiple messages includes: a wireless transceiver; an output unit; a memory for storing a multi-message unifying interface program, a multi-message unifying program, transmitting messages, receiving messages, and a unified message; an input unit for receiving a selection signal for selecting one or more transmitting/receiving messages or a multi-message unifying menu key through a multi-message unifying interface; and a controller for driving the multi-message unifying interface program and the multi-message unifying program, and generating single unified message by unifying the selected transmitting/receiving messages selected according to the selection signal.

Abstract: A jelly-roll type electrode assembly having a negative electrode plate having a negative electrode coated portion coated with a negative electrode active material layer, and a negative electrode uncoated portion disposed at an end of the negative electrode plate that is near a center of the electrode assembly, a positive electrode plate having a positive electrode coated portion coated with a negative electrode active material layer, and a positive electrode uncoated portion disposed at an end of the positive electrode plate that is near the center of the electrode assembly, a separator between the negative electrode plate and the positive electrode plate, and a negative electrode tab and a positive electrode tab electrically connected to the negative electrode uncoated portion and the positive electrode uncoated portion, respectively, wherein a width of the negative electrode uncoated portion is approximately 2 to 3 times that of the negative electrode tab.

Abstract: A method of preparing a lithium secondary battery including a multi-phase separator having a gelled polymer uniformly impregnated therein, includes surface-treating a porous separator to provide a coated weight of a gelled polymer less than or equal to 20 mg/cm2, by impregnating the porous separator into a gelled polymer solution containing less than or equal to 5 wt % of the gelled polymer based on a weight of an organic solvent. The separator is interposed between a cathode and an anode to prepare an electrode assembly. The electrode assembly is placed into a housing, an electrolytic solution is injected into the housing, followed by sealing and curing a resultant structure.

Abstract: A secondary battery includes positive electrode plates with tabs at one end, bundled together, negative electrode plates with tabs at one end, bundled together, a separator between each positive electrode and each negative electrode, a protective circuit controlling charging/discharging of the battery, and a pair of electrical leads, each lead including two layers of different materials such that one layer is connected to one of the tabs and the other layer is connected to the protective circuit.
