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.

Abstract: A battery cell assembly includes a pouch-shaped battery cell, a cell housing configured to receive the pouch-shaped battery cell, a blocking plate located at each of opposite ends of the cell housing in a length direction, and a venting plate configured to discharge gas emitted from the pouch-shaped battery cell. A thermal expansion material is located along an inner surface of the blocking plate, whereby it is possible to completely block transfer of flames generated from the pouch-shaped battery cell and to discharge gas in a direction toward the venting plate.
