Abstract: A manufacturing method of a lithium secondary battery includes assembling a battery cell by accommodating an electrode assembly inside a battery case; injecting an electrolyte; and pre-aging the battery cell after the electrolyte is injected. The pre-aging includes applying sound waves to the battery cell using a speaker; and aging the battery cell.

Abstract: The present invention comprises: a pre-aging step for aging, at room temperature, a secondary battery comprising a cathode including a cathode active material, an anode including an anode active material, a separator interposed between the cathode and the anode, and an electrolyte (S100); a first charging step for primarily charging the pre-aged secondary battery to an SOC of the secondary battery of 60% or higher (S200); a high-temperature aging step for aging the primarily charged secondary battery at a high temperature (S300); and a room-temperature aging step for aging the high-temperature aged secondary battery at room temperature (S400), wherein the room-temperature aging step comprises a resetting process for charging the secondary battery to the same SOC as in the first charging step.

Abstract: A secondary battery activation method includes a pre-aging step for aging, at room temperature, a secondary battery comprising a positive electrode comprising a positive electrode active material, a negative electrode comprising a negative electrode active material, a separator disposed between the positive electrode and the negative electrode, and an electrolyte; a charging step for primarily charging the pre-aged secondary battery to 60% or more of state of charge (SOC) of the secondary battery; a high-temperature aging step for aging the primarily charged secondary battery at a high temperature; and a room-temperature aging step for aging, at room temperature, the secondary battery which has been aged at a high temperature, wherein the high-temperature aging step is performed at a temperature of 60° C. or higher.

Abstract: A secondary battery activation method, which calculates an appropriate initial charge rate (SOC) and a high-temperature aging time according to the size of the secondary battery during the activation process, and in the case of an activation process using the same, by efficiently removing gas generated inside an electrode assembly while charging, provides an effect of improving the charging uniformity of an electrode in a subsequent charging stage and increasing the usable capacity of the battery.

Abstract: A time-dependent information management system and method for a mobile phone that enable the management of time-related information in consideration of a change of time zone are provided. The method includes registering an event planned to occur at a first local time based on a first time zone together with a reference time calculated from the first local time; if the mobile phone enters into a second time zone, selecting the event in accordance with a key input; and setting the event to occur at a second local time calculated from the reference time. The system and method enable selectively adapting, when a mobile phone moves from a first time zone to a second time zone, times of schedules planned in the first time zone to a local time of second time zone, thereby effectively managing the schedules in multiple time zone-crossing environment.

Abstract: The present invention relates to an immuno-therapeutic and prophylactic vaccine comprising monocytes or immature myeloid cells (IMCs) loaded with the ligand of natural killer T cell and an antigen for the prevention and treatment of infectious disease or cancer, more precisely, an immuno-therapeutic and prophylactic vaccine comprising monocytes or IMCs loaded with ?-galactosylceramide (?GalCer), a kind of glycolipid and a natural killer T cell ligand, and antigen. Monocytes or immature myeloid cells (IMCs) therein, which are easily obtainable, unlike dendritic cells, not only induce a significant level of cytotoxic T lymphocyte responses but also have a prophylactic and therapeutic effect on malignant tumor. Therefore, the immuno-therapeutic and prophylactic vaccine of the present invention can be effectively used as an immunotherapeutic agent.
