WIPO Patent Application WO/2023/158173
Kind Code:
A1
Abstract:
The present invention relates to a secondary battery manufacturing device and a secondary battery manufacturing method using same, and, more specifically, to a secondary battery manufacturing device for slitting an electrode, and a secondary battery manufacturing method using same. The present invention provides the secondary battery manufacturing device, which further comprises: at least one unwinder unit for unwinding an electrode sheet on which an electrode active material is applied and dried; at least one first slitting unit, which receives the electrode sheet from the unwinder so as to primarily cut the electrode sheet, and thus forms a plurality of first unit electrode sheets; at least one second slitting unit, which receives the first unit electrode sheets from the first slitting unit so as to secondarily cut the first unit electrode sheets, and thus forms a plurality of second unit electrode sheets; at least one rewinder for receiving the second unit electrode sheets from the second slitting unit and winding same; and a frame unit having a slitting space provided therein, wherein the first slitting unit and the second slitting unit are provided in the frame unit.
