The present disclosure relates to a super absorbent polymer having a high water content and a method for preparing the same. The super absorbent polymer according to the present disclosure has a relatively high water content compared to a conventional one but has no degradation in absorption-related physical properties, and thereby can be used in various fields.

Super absorbent polymer and method for preparing same

An insulation-coating overlay control system, an electrode plate for a secondary battery, and an insulation-coating overlay control method are provided. The 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.
