    摘要： Provided are a mixed cathode active material including lithium manganese oxide expressed as Chemical Formula 1 and a stoichiometric spinel structure Li4Mn5O12 having a plateau voltage profile in a range of 2.5 V to 3.3 V, and a lithium secondary battery including the mixed cathode active material. The mixed cathode material and the lithium secondary battery including the same may have improved safety and simultaneously, power may be maintained more than a required value by allowing Li4Mn5O12 to complement low power in a low state of charge (SOC) range. Therefore, a mixed cathode active material able to widen an available SOC range and a lithium secondary battery including the mixed cathode active material may be provided and properly used in a plug-in hybrid electric vehicle (PHEV) or electric vehicle (EV).

    摘要： A high capacity lithium secondary battery includes a lithium manganese oxide having a layered structure exhibiting a great irreversible capacity in the event of overcharging at a high voltage and a spinel-based lithium manganese oxide. Because it is activated at a high voltage of 4.45 V or higher based on a positive electrode potential, additional lithium for utilizing a 3V range of the spinel-based lithium manganese oxide can be provided and an even profile in the entire SOC area can be obtained. Because the lithium secondary battery includes the mixed positive electrode active material including the spinel-based lithium manganese oxide and the lithium manganese oxide having a layered structure, and is charged at a high voltage, its stability can be improved. Also, the high capacity battery having a large available SOC area and improved stability without causing an output shortage due to a rapid voltage drop in the SOC area can be implemented.

    摘要： A thin and wide area lithium ion secondary battery is disclosed. The lithium ion secondary battery has a container having a flange extended outwardly from a region where a terminal is located in the container, and constituted by a can and a cap having preferred shapes, respectively, wherein the flange of the cap is welded at an outer surface of the flange to an outer surface of the flange of the cap by means of micro-arc welding. According to the present invention, a cooling jig can be easily installed to the container, allowing efficient removal of problems caused by heat upon welding, resulting in allowing application of micro-arc welding thereto without generating damage of the interior or the battery caused by heat. Accordingly, more economical and stable butt welding can be performed, thereby remarkably reducing defect occurrence rates causing leakage problem of the resulting battery, and manufacturing costs of the lithium secondary battery.
