| 摘要 |
The present invention provides a method for manufacturing a secondary cell, comprising the steps of: disposing two sheets of separators (10) above and below a negative electrode plate (30), disposing a positive electrode plate (40) above the upper separator (10) or below the lower separator (10), and supplying elongated each one end of the separators (10), the negative electrode plate (30), and the positive electrode plate (40) to a mandrel (20) along the same transfer line; punching each vertical one end and/or the other end of the negative electrode plate (30) and the positive electrode plate (40), which intersects the transfer direction of the negative electrode plate (30) and the positive electrode plate (40) continuously supplied, to form a plurality of negative electrode tabs (32) on the negative electrode plate (30) by a predetermined gap (g) and form a plurality of positive electrode tabs (42) on the positive electrode plate (40) by a predetermined gap (g); winding the stacked body (S) of the separator/negative electrode plate/separator/positive electrode plate altogether by the mandrel (20) to produce an electrode assembly (50) having one side on which the plurality of negative electrode tabs (32) and the positive electrode tabs (42) are stacked; separating the mandrel (20) from the electrode assembly (50), and transferring the electrode assembly (50) by a holding unit; and cutting the separator/negative electrode plate/separator/positive electrode plate connected to the electrode assembly (50) |
