STACKING DEVICE FOR SECONDARY BATTERY, STACKING METHOD USING SAME, AND SECONDARY BATTERY OBTAINED THEREBY

Various embodiments of the present invention provide a stacking device for a secondary battery configured to stack electrode plates at a high rate, a stacking method using the same, and a secondary battery obtained thereby. As an example, disclosed are a stacking device for a secondary battery, a stacking method using the same, and a secondary battery obtained thereby, the stacking device comprising: a first electrode plate bonded body supply portion for supplying a first electrode plate bonded body comprising a first electrode plate, which comprises a first electrode first coating portion and a first electrode second coating portion positioned to be spaced apart from the first electrode first coating portion, and separators stacked on both surfaces of the first electrode plate; a second electrode plate supply portion for arranging a second electrode first coating portion and a second electrode second coating portion of a second electrode on both surfaces of the first electrode first coating portion of the first electrode plate bonded body, respectively, thereby forming a unit cell; and a folding portion for folding the first electrode plate bonded body, which has the unit cell formed thereon, such that the second electrode first coating portion or the second electrode second coating portion of the second electrode plate faces the first electrode second coating portion of the first electrode plate, thereby forming a stack.
