The range of variation in the difference between the envelope lines on the same side of the positive and negative electrode sheets within the core pack is referred to as "EU" (Envelope Uniformity).

The alignment degree between the separator and the positive or negative electrode within the core pack is referred to as "FU" (Alignment Uniformity).

The relative position difference within the core pack between electrode sheets and electrode sheets, as well as between electrode sheets and the separator, where they overlap.

The relative position error in the overlap of material rolls (positive electrode sheets, negative electrode sheets, separators, tapes).

The relative position error in the overlap of multiple tab or tab-like features within the core pack.

The part of the negative electrode sheet that extends beyond the positive electrode sheet in either the length or width direction.
