Abstract
A press jig includes a pair of plate-shaped members, each of which includes a plurality of protrusions spaced apart from each other on a surface thereof, the protrusions being configured to come into contact with the secondary battery when pressed; and a heating unit that heats the protrusions formed on the plate-shaped member. A method of manufacturing a secondary battery using the same is also provided.
Claims14
A pressurizing jig for inserting a secondary battery between a pair of plate-shaped members facing each other in a cell activation process of the secondary battery and pressing the secondary battery from opposite sides, the pressurizing jig comprising:
- the pair of plate-shaped members, each plate shaped member having:
- a plurality of protrusions spaced apart from each other on a surface thereof, the protrusions being configured to be in contact with the secondary battery when the plate-shaped member is pressed into contact with the secondary battery;
- and
- a heating unit configured to heat the protrusions formed on the plate-shaped member,
- wherein the plurality of protrusions formed on the plate-shaped member are formed in a dot patterned structure.
