System for and method of manufacturing lithium ion secondary battery

A lithium ion secondary battery manufacturing system comprising:

• a single chamber comprising:
• lithium ion secondary battery;
• a charging/discharging device configured to electrically charge and discharge the lithium ion secondary battery;
• a pressure plate configured to press the lithium ion secondary battery when the lithium ion secondary battery is electrically charged;
• a pointed portion configured to bore a hole in a pouch of the lithium ion secondary battery to allow gas generated during the electrical charging of the lithium ion secondary battery to be removed from the pouch when the lithium ion secondary battery is pressed by the pressure plate;
• a sealer configured to seal the pouch of the lithium ion secondary battery by closing the hole after the gas is removed;
• a temperature control device configured to control an internal temperature of the chamber;
• and
• multiple drive devices configured to drive the pressure plate, the pointed portion, and the sealer;
• wherein when the lithium ion secondary battery is electrically charged by the charging/discharging device, the controller operates the pressure plate to press the lithium ion secondary battery, operates the temperature control device to raise or lower the internal temperature of the chamber, and operates the pointed portion to bore the hole in the pouch of the lithium ion secondary battery to enable the gas to be removed from the pouch in real time.
