Process material utilization

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

Actions taken to eliminate the causes of potential non-conformance or other potential undesirable situations.

The uniformity tolerance of the thickness of the coated material on a web after drying is categorized based on the coating process into single-side dry thickness tolerance and double-side dry thickness tolerance, depending on whether it is a single-sided or double-sided coating.

Product critical parameters and performance refer to the key aspects or characteristics of a product that are essential for its functionality and quality. This can include features such as functionality, performance parameters, design, and external appearance, among others.

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

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