The explosive growth of new energy vehicles has made laser marking machines indispensable tools for creating the “identity cards” of power batteries.

Permanent, clear traceability markings safeguard safety and quality.

With the rapid global development of the new energy vehicle industry, the safety and traceability of power batteries—the industry's “heart”—have been elevated to unprecedented importance. Against this backdrop, laser marking technology, with its irreplaceable advantages, has become an indispensable component in power battery manufacturing lines, injecting robust momentum into the industry's safe and standardized development.

Pain Points of Traditional Marking and Breakthroughs in Laser Marking

In power battery production, each cell, module, and battery pack requires a unique “identity card”—typically a QR code or serial number. Traditional marking methods like inkjet printing suffer from issues such as wear and tear, peeling, potential chemical contamination of batteries, and high maintenance costs. These risks are absolutely unacceptable for power batteries requiring full lifecycle monitoring.
Fiber laser marking machines, however, use high-energy laser beams to create permanent markings directly on battery casings, electrodes, chips, and other materials. This marking never wears off or peels, withstands electrolyte corrosion and prolonged friction, ensuring clear traceability throughout the entire lifecycle—from production and use to recycling. Additionally, laser marking is a non-contact process requiring no consumables or chemicals, fully meeting the cleanliness and safety standards for power battery manufacturing.

Empowering Smart Manufacturing, Building a Full-Chain Traceability System

For battery manufacturers, laser marking transcends mere identification—it serves as a critical gateway to Industry 4.0 smart factories. Laser marking equipment seamlessly integrates with MES (Manufacturing Execution Systems) and ERP (Enterprise Resource Planning Systems), enabling automated coding and data correlation.
Scanning the laser-marked QR code provides real-time access to comprehensive production information, including batch details, raw material origins, process parameters, and test data. This not only significantly enhances production management efficiency and quality control standards but also enables swift, precise recalls during quality incidents, minimizing losses and safeguarding brand reputation.
