Electric Vehicle Battery
In 2024, the global capacity of installed power batteries reached 895 GWh, a year-on-year increase of 27.2%. Currently, prismatic, pouch, and cylindrical batteries coexist and the industry is advancing toward green, low-carbon, and high-quality development. In the future, power battery production will focus more on the application of intelligent, automated, and flexible technologies, striving for excellence in quality control at every production stage from individual cells to battery packs. Defect inspection, as a core part of quality control, is an indispensable component.

The welding quality of battery sealing nails critically impacts battery performance. Defects such as pinholes, cracks, burst points, pits, lifted nails, steps, discoloration, weld ash, incomplete welds, and slag may occur after welding, potentially causing loose casings, air leaks, or electrolyte le -
Defect inspection is critical in electrode production processes like die-cutting and winding, where minor defects—including metallic/non-metallic contaminants, white spots, bubbles, dark spots, decarburization, scratches, leakage, and damage—can adversely affect battery electrochemical performance. -
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 -
Structural adhesive layers in lithium battery modules secure and protect internal components. Defects like bubbles or cracks can reduce performance or cause safety risks. Current quality inspection requires destructive dismantling after adhesive curing, resulting in waste. Due to the adhesive’s high -
Minor defects—such as pinholes, explosion points, or protrusions—in power battery top covers can compromise sealing, leading to electrolyte leakage or short circuits, which severely impact battery performance and safety.Manual inspection lacks consistency, resulting in production risks and customer -
In power batteries, the blue protective film (industry-called "blue film") is a core outer layer material, ensuring fixation, insulation, dustproofing, and waterproofing as a key barrier between cells and the environment. Yet scratches, damage, contamination, wrinkles, or depressions often occur, ha
