Battery Manufacturing Terminology
A control and management model by customers for the supplier's supply process, which specifies the process and requirements for customer approval of production parts and bulk materials, providing normative guidance for the organization to provide samples and documents to customers.
Quality characteristics that, if they exceed the specified value requirements, would directly impact product safety or lead to the loss of the product's overall functionality.
Quality characteristics that, if they exceed the specified value requirements, would result in the partial loss of product functionality.
Quality characteristics that, if they exceed the specified value requirements, do not immediately affect product functionality but may lead to a gradual loss of product functionality over time.
The sheets that have been coated and dried are sequentially wound into rolls in accordance with specified speed and tension requirements.
The sheets are maintained in the correct alignment and position during coating or drying by deflecting their path direction through the angle adjustment of rollers.
During coating or drying, the alignment and position of the sheets are maintained correctly through the method of deflecting the sheet path direction and position by adjusting the angles of the rollers.
During the unwinding or rewinding process, the alignment and direction of the sheets are maintained correctly, or the specified winding evenness is achieved by the linear movement of the reel stand.
Force is applied to the sheets during unwinding, coating, and rewinding processes to ensure the sheets are laid flat and maintain their direction.
In the core pack manufacturing process, the alignment of all positive or negative electrode sheets along the envelope edges in the length and width directions is referred to as "CU" (Cathode Alignment) for positive electrodes and "DU" (Anode Alignment) for negative electrodes.
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.
