Abstract
(EN)
A method for manufacturing a secondary battery is disclosed. According to one aspect of the invention, provided is a method for manufacturing a secondary battery, comprising: a first step of preparing a top cap and a safety vent; a second step of bending the ends of the safety vent upward; and a third step of inserting the top cap into the safety vent, wherein the outer diameter (A) of the top cap is larger than the inner diameter (B) of the safety vent between the second step and the third step.
