The present invention provides a method of manufacturing a lithium secondary battery including a step of activating a lithium secondary battery, wherein the lithium secondary battery includes a positive electrode, a negative electrode and a separator, and a binder layer is formed on one surface, The activation process includes a process of applying pressure and heat to the lithium secondary battery, and the process of applying heat may include a process in which the temperature of the lithium secondary battery is higher than the heat distortion temperature (HDT) of the binder of the binder layer ), Wherein the method for producing a lithium secondary battery according to the present invention includes a step of applying pressure and heat during an activation process of a lithium secondary battery, Can be released to the outside of the battery, and the interface structure between the electrode and the electrolyte can be stabilized. Therefore, the lithium secondary battery It may be useful in the preparation. |
