[0002] The battery cell is an important component of lithium battery components, equivalent to the heart of the lithium battery. Its production quality requirements are high, and any surface defects may affect the performance and safety of the battery. The battery cell is prone to scratches, pits and other defects during the production process, so the battery cell needs to be inspected for appearance before leaving the factory to ensure the factory quality of the battery.
