Abstract: The present invention relates to a method for manufacturing an electrode assembly. The method for manufacturing the electrode assembly comprises: a step (a) of transferring a plurality of radical units one by one from a first set position to a second position; a step (b) of measuring a distance between a full width end that is an end of the first electrode in a full width direction and a full width end that is an end of the second electrode in a full width direction; a step (c) of measuring a distance (B1) from a reference point (O) of the second set position to the full width end of the first electrode of the first radical unit; a step (d) of stacking the second radical unit on the first radical unit; a step (e) of measuring a distance (B2) from the reference point (O) of the second set position to the full width end of the first electrode of the second radical unit; a step (f) of measuring a distance (C1) between the full length end of the first electrode of the first radical unit and the full width end of the second electrode of the second radical unit by adding the distances (B2, A2) to each other and subtracting the distance (B1) from the sum of the distances (B2, A2); and a step (g) of comparing the distances (C1, A1) to each other to determine whether stacking is defective.

Abstract: An insulation-coating overlay control system, an electrode plate for a secondary battery, and an insulation-coating overlay control method are provided. I system includes an insulation coater configured to coat an insulating material to allow the insulating material to cover a partial region of a coated part and a non-coated part in an electrode plate along a boundary part. The coated part has an electrode slurry coated thereon and the non-coated part does not have the electrode slurry coated thereon. An insulation-coating width measuring means is configured to measure an overlay width. An insulation coater moving means is configured to move the insulation coater and a controller is configured to control the insulation coater moving means to adjust the overlay width by comparing the measured overlay width with a predetermined overlay width setting range or an overlay width reference value.
