Abstract
Disclosed is a method for manufacturing a secondary battery (10) containing a nonaqueous electrolyte solution. This method comprises a step (S110) for preparing an electrode assembly (20) having positive and negative electrode sheets (30, 40), a step (S120) for immersing the electrode assembly (20) into a nonaqueous liquid (60), and a step (S130, S140) for placing the electrode assembly (20) after immersion into a battery container (11) together with a nonaqueous electrolyte solution (70). By performing the immersion process, the water content in the electrode assembly (20) moves into the nonaqueous liquid (60).
