摘要： Disclosed is a lithium secondary battery comprising an electrode assembly composed of a cathode, an anode and a separator, and a lithium electrolyte, wherein the electrodes and/or electrolyte include a compound (“urethane compound”) and/or polymer (“poly urethane”) which are decomposed upon overcharge of the battery and contain a urethane group in a molecular structure thereof. The lithium secondary battery of the present invention is characterized by addition of a compound or polymer having a urethane group to electrodes and/or electrolyte, wherein the thus-added compound and/or polymer have substantially no adverse effects on general performance of the battery under normal operating conditions and are decomposed with high reliability upon overcharge of the battery, thereby offering time delay effects for securing battery safety, and the decomposition products thereof result in sharply increased internal resistance of the battery, thereby increasing battery safety.

摘要： Disclosed herein is a secondary battery including an electrode assembly that can be charged and discharged, wherein the electrode assembly includes an electrode (‘safety electrode’) composed of a material that effects an electrochemical reaction when the secondary battery is overcharged (Overcharge reaction material’). The safety electrode according to the present invention is not directly added to components related to the operation of the secondary battery. Consequently, the safety electrode does not deteriorate the performance of the battery during the normal operation of the battery, and the safety electrode consumes the overcharge current through the electrochemical reaction, when the battery is overcharged, whereby the safety of the battery is fundamentally secured.

摘要： Disclosed herein are a secondary battery including an electrode assembly for charging and discharging mounted in a sheathing member including a metal layer and a resin layer, wherein the secondary battery further includes a secondary battery having a molding part of a predetermined thickness at least partially formed at the outside of a sheathing member, preferably, at a sealing region of the sheathing member, and a medium- or large-sized battery pack including the same. The molding part is formed at the outside of the sheathing member of the secondary battery. Consequently, the secondary battery according to the present invention has high mechanical strength, and therefore, it is possible to construct a battery pack without using addition members, such as cartridges. When the molding part is formed at the sealing region, which is weak, the molding part increases the mechanical strength and the sealing force of the secondary battery. Consequently, a battery pack including the secondary batteries as unit cells can be manufactured generally in a compact structure and with relatively small weight, and the assembly process of the battery pack is greatly simplified. The battery pack according to the present invention has high structural stability. Consequently, the battery pack can be preferably used as a power source for electric vehicles, hybrid electric vehicles, electric motorcycles, and electric bicycles.
