摘要： Disclosed is a method for producing a lithium secondary battery including forming an electrode assembly using a cathode, an anode and a separator, introducing the electrode assembly into a battery case, injecting an electrolyte into the battery case, and sealing the battery case, wherein, during assembly of the electrode assembly, insulating particles are dispersed on part of the surface of the separator, or at least one of the cathode and the anode contacting the separator. The step of dispersing insulating particles on the part of the surface of the separator or at least one of the cathode and the anode contacting the separator during battery assembly can considerably reduce short-circuits in a lithium secondary battery caused by intrinsic and extrinsic factors and thus low-voltage defects, and thereby significantly improve yield of a lithium secondary battery.

摘要： Provided are a pouch-type secondary battery having improved safety, and a battery pack including the pouch-type secondary battery. When inner pressure of a pouch is increased by an overdischarge, the pouch is deformed to separate electrode leads from electrode tabs. When the secondary battery is manufactured, an additional material or device is unnecessary. In addition, since the pouch-type secondary battery fundamentally cuts off electric current when gas is generated therein, the service life and safety of the secondary battery can be significantly improved, and the manufacturing costs and the weight thereof can be reduced. Furthermore, the shape of the secondary battery can be easily modified.
