In the lithium battery industry, barcode reading typically refers to scanning QR codes or barcodes on battery cells. This process retrieves critical information including battery identification, production dates, and batch numbers, enabling product traceability and quality control. Industrial-grade barcode readers are employed to meet complex environmental demands and high-precision requirements. Common scanning methods include laser scanning and image recognition. Laser scanners achieve fast, accurate code reading, while vision-based readers utilize image analysis for higher precision decoding. With the rapid advancement of lithium battery technology, barcode reading has become widely adopted. On production lines, readers verify unique battery identifiers, ensuring traceability for quality assurance. The technology also enables full supply chain tracking—from raw materials to end consumers—enhancing product reliability through comprehensive data recording. As a critical industrial application, barcode reading technology: Ensures product traceability (ISO 9001 compliance) Enhances quality monitoring (IEC 62133 standards) Boosts production efficiency (30% faster than manual checks) Improves product quality (<0.01% misidentification rate)
