Abstract: A lithium secondary battery includes a cathode including a cathode active material that contains lithium metal oxide particles, an anode facing the cathode, and a non-aqueous electrolyte solution including a non-aqueous organic solvent that contains a fluorine-based organic solvent and a lithium salt. A ratio of the number of moles of lithium contained in each of the lithium metal oxide particles to the total number of moles of metals excluding lithium contained in each of the lithium metal oxide particles is 1.05 or more. A content of the fluorine-based organic solvent is in a range from 5 vol % to 60 vol % based on a total volume of the non-aqueous organic solvent.

Abstract: A method, a system and a mobile terminal for providing data services, whereby specific data services according to a zone of a precinct wireless network are conveniently provided to mobile terminal subscribers in the precinct wireless network, while preventing the maintenance of an unnecessary connection of the terminal to the precinct wireless network. When a mobile terminal enters the precinct wireless network, at least one application program corresponding to a predetermined data service function of the mobile terminal is automatically executed, and thereafter when the terminal exits the precinct wireless network, the application program is automatically terminated. In addition, the terminal opens a data channel connection with the precinct wireless network only when the data service is currently executed in it.
