Abstract
A method for manufacturing a secondary battery includes accommodating an electrode assembly in a battery case including an accommodation part and a gas pocket part connected to the accommodation part to collect a gas generated in the accommodation part, performing sealing along an outer circumferential surface of the battery case except for an end of the gas pocket part, injecting an electrolyte into the accommodation part through the end of the gas pocket part, performing double sealing on the end of the gas pocket part so that a first sealing part is formed at a side closer to the accommodation part, and a second sealing part is formed at a side that is farther from the accommodation part, removing a portion, on which the second sealing part is formed, from the battery case, and applying electricity to the electrode assembly to charge the secondary battery.
