摘要： Disclosed is a method for producing a lithium secondary battery, the method comprising the steps of: (a) distributing or scattering insulating powder partially or totally onto a surface of at least one of a cathode, an anode and a separator; (b) forming an electrode assembly by using the cathode, the anode and the separator; and (c) introducing the electrode assembly into a casing and sealing the casing. A lithium secondary battery obtained from the method is also disclosed. The method for manufacturing a lithium secondary battery, including a step of scattering insulating powder partially or totally onto the surface of a separator or the surface of at least one electrode facing to the separator, significantly reduces generation of an internal short circuit between both electrodes caused by internal or external factors during the assemblage of a battery and generation of low-voltage defects, and thus significantly improves yield of desired batteries.
