Battery laser marking technology uses high-energy laser beams to permanently code information on plastic shells or poles. The marking content mainly includes key data such as model specifications, production date, batch number, unique serial number, and safety certification mark. The marking depth formed by this technology is moderate, clear and wear-resistant, with strong acid corrosion resistance, high temperature resistance and vibration resistance. It can effectively resist the erosion of internal chemical substances and complex working environments in the battery, ensuring that the information is clear and identifiable throughout the entire product life cycle and cannot be easily tampered with. This permanent identification provides a solid and reliable data foundation for product production traceability, quality control, anti-counterfeiting verification, and after-sales service, and is an important link in ensuring industry safety and brand reputation.
