摘要： Disclosed is the structure of a center pin assembly inserted into the winding center of a winding-type electrode assembly of an electrochemical device, which has a case containing the winding-type electrode assembly. The center pin assembly can secure the safety of an electrochemical device when physical impact (e.g. squeezing, shock) is applied from the outside, when the internal temperature rises, and/or when the device is overcharged. The center pin assembly includes a center pin manufactured by winding a planar substrate into a tubular shape, the planar substrate having at least two protrusions formed in an embossing type or at least two discontinuous scores formed in a predetermined shape; and a container placed in a space inside the center pin, the container containing a substance capable of improving the safety of the device.

摘要： The present invention provides a cathode comprising two or more lithium-containing metal composite oxides, having different potentials versus lithium (Li/Li+) and different impedances, the cathode comprising: (a) a first lithium-containing metal composite oxide; and (b) a second lithium-containing metal composite oxide, which has a high impedance and low potential versus lithium (Li/Li+), compared to those of the first lithium-containing metal composite oxide. In the invention, two or more lithium-containing metal composite oxides are used in combination as cathode components in a battery, whereby, when a short circuit occurs in the battery, the instantaneous flow of a large amount of current can be minimized and, at the same time, the accumulation of heat in the battery can be reduced, thus ensuring the safety of the battery.

摘要： Disclosed are a cathode active material and a secondary battery including the same. Herein, the cathode active material includes (a) a first lithium-containing metal composite oxide and (b) a second lithium-containing metal composite oxide coated on an entire particle surface of the first lithium-containing metal composite oxide, the second lithium-containing metal composite oxide having a higher resistance and a lower potential vs. lithium potential (Li/Li″ 1) than the first lithium-containing metal composite oxide. In the disclosed cathode active material, an entire surface of a first lithium-containing metal composite oxide is coated with a second lithium-containing metal composite oxide having a high resistance value and a low potential vs. lithium potential. Therefore, during an internal short of a secondary battery, it is possible to slow down the moving rate of a large amount of lithium ions and electrons from an anode to a cathode, and thus to prevent heat generation caused by the occurrence of temporary over-current. Also, it is possible to increase the temperature where a cathode active material is decomposed and gas is generated, and to improve thermal stability by inhibiting side reactions of the cathode active material and electrolyte.
