Method for Manufacturing Secondary Battery with Improved Resistance

The present invention relates to a method of manufacturing a secondary battery with improved resistance. According to the present invention, since the electrode assembly with succinonitrile interposed at the interface between the electrode and the separator is manufactured and then laminated, a high-pressure process is not required during lamination compared to the prior art, thereby improving processability, and since succinonitrile is dissolved in the electrolyte solution, it exhibits an effect of improving the resistance of the battery.
