Abstract
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.
Claims12
A method for manufacturing a secondary battery, comprising:
- preparing an electrode assembly in which succinonitrile is deposited alone on a separator or an electrode, thereby interposing the succinonitrile at an interface between the electrode and the separator;
- laminating by heating and pressing the prepared electrode assembly;
- and
- preparing the secondary battery by accommodating the laminated electrode assembly in a battery case and injecting an electrolyte solution.
