Cylindrical lithium-ion batteries offer market advantages due to mature technology and high standardization. However, to maintain competitiveness, manufacturers must improve production quality and adopt smart manufacturing strategies. Defects such as scratches, black spots, contamination, ring marks, short circuits, and edge deformations require strict inspection to ensure safety and reliability.
Key challenges include the complex surface characteristics of cylindrical batteries—such as reflectivity and curvature—which affect imaging quality and defect recognition. The wide variety of defects in size, shape, and location demands high-precision inspection systems. Additionally, increasing production scale and automation require faster and more efficient inspection capabilities.
