Overall material utilization

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).

Force is applied to the sheets during unwinding, coating, and rewinding processes to ensure the sheets are laid flat and maintain their direction.

Actions taken to eliminate the factors that have been identified as causing non-conformance in a product.

The continuous sheets (foils, separators, tapes, etc.) are unwound in a specified order with a controlled speed and tension and fed into the coating process.

The percentage of cells that meet the requirements for grouping and pairing in relation to the initial input of cells in the production of cells.

It refers to the production capacity of equipment per unit of time, typically measured in parts per million (PPM).
