With the rapid popularization of smart digital devices, new energy vehicles and energy storage equipment, lithium-ion batteries are widely used in smartphones, laptops, new energy vehicles, portable energy storage and other terminal products due to their high energy density, long cycle life and portability. As the global lithium battery industry continues to expand, countries have imposed stricter controls on battery safety and production compliance. In this context, CB Certification (CB Scheme), an internationally recognized certification, has become a core compliance credential for lithium-ion batteries to enter the global market and ensure safe product circulation.
CB Certification is a global electrical product safety certification system implemented by the International Electrotechnical Commission (IEC). Its core function is to verify whether electronic and electrical products meet international general electrical safety standards, making it one of the most recognized product safety certifications worldwide. For lithium-ion battery manufacturers, obtaining CB Certification is of irreplaceable practical significance:
1、It is a mandatory access threshold for product circulation in many markets; most overseas countries and regions explicitly require compliant CB Certification for lithium battery products on the market.
2、Certified products greatly enhance brand credibility and market reputation, establishing quality advantages over competitors.
3、Relying on the international mutual recognition advantage of CB Certification, enterprises can simplify the multi-country certification transfer process, significantly reduce compliance costs for overseas expansion, and efficiently expand overseas trade channels.
Before applying for CB Certification for lithium-ion batteries, enterprises must prepare a complete set of application materials to ensure smooth review:
1、Product certification application form
2、Detailed specifications of battery cells and finished batteries
3、Circuit drawings of battery protection boards
4、List of core components
5、Enterprise ISO 9001 quality management system certification
6、Product safety risk analysis reports and other technical documents
7、Test samples: 53 battery cells and 25 finished lithium batteries
The entire CB Certification process is standardized and clear, divided into six steps:
1、Conduct pre-product evaluation to verify whether product parameters and structural design meet the international standards for CB Certification.
2、Organize all technical materials and test samples to complete preliminary preparations.
3、Select a formal third-party testing laboratory with CB Certification authorization.
4、Send samples to the laboratory for full compliance testing of safety and electrical performance.
5、The testing institution verifies test data and issues an authoritative CB test report.
6、The enterprise formally submits a certification application with a qualified test report, and obtains the official CB Certification certificate upon approval.
In summary, as a core supporting product of the new energy industry, lithium-ion batteries rely on safety performance and compliance qualifications for long-term development. CB Certification is not only a mandatory pass for lithium batteries to legally enter the international market, but also an important tool for enterprises to control product quality, avoid overseas market compliance risks and establish a high-quality brand image. Through the standardized CB Certification system, lithium battery enterprises can strictly control product safety and quality, further expand global sales, and consolidate their development advantages in the increasingly fierce international new energy market competition.
