▍What is CE Certification?

The CE mark is a “passport” for products to enter the EU market and the EU Free Trade Association countries market. Any stipulated products (involved in the new method directive), whether manufactured outside the EU or in EU member states, in order to circulate freely in the EU market, they must be in compliance with the requirements of the directive and relevant harmonized standards before being placed on the EU market , and affix the CE mark. This is a mandatory requirement of EU law on related products, which provides a unified minimum technical standard for the trade of products of various countries in the European market and simplifies trade procedures.

▍What is CE directive?

The directive is a legislative document established by the European Community Council and the European Commission under authorization of the European Community Treaty. The applicable directives for batteries are:

2006/66 / EC & 2013/56 / EU: Battery Directive. Batteries that comply with this directive must have a trash can mark;

2014/30 / EU: Electromagnetic Compatibility Directive (EMC Directive). Batteries that comply with this directive must have the CE mark;

2011/65 / EU: ROHS directive. Batteries that comply with this directive must have the CE mark;

Tips: Only when a product complies with all CE directives (the CE mark needs to be pasted), can the CE mark be pasted when all the requirements of the directive are met.

▍The Necessity of Applying for CE Certification

Any product from different countries that wants to enter the EU and the European Free Trade Zone must apply for CE-certified and CE marked on the product. Therefore, CE certification is a passport for products entering EU and the European Free Trade Zone.

▍Benefits of Applying for CE certification

1. EU laws, regulations, and coordinate standards are not only large in quantity, but also complex in content. Therefore, obtaining the CE certification is a very smart choice to save time and effort as well as to reduce the risk;

2. A CE certificate can help earning the trust of consumers and market supervision institution to a maximum extent;

3. It can effectively prevent the irresponsible allegations situation;

4. In the face of litigation, the CE certification will become legally valid technical evidence;

5. Once punished by EU countries, the certification body will jointly bear the risks with the enterprise, thus reducing the risk of the enterprise.

On December 22, updated IEEE 1725 were officially posted on the CTIA certification website as following
CRD Document: IEEE 1725 Version 3.0 —— Requirements for CTIA Battery System Compliance CertificationCRSL Document: IEEE 1725 Certification Requirements Status List and Worksheet (CRSL1725 Version 221222)
PRD Document: Battery Compliance Certification Requirements Document Version 6.1
Among them, the CRD and CRSL documents are updated as optional certification with a 6-month transition period. For the content changes of the new CTIA IEEE 1725, please refer to previous issues of the monthly magazine.The electrolytes used in commercial lithium-ion batteries are considered to be one of the factors to the safety hazards of lithium batteries. These electrolytes are generally organic carbonate solvents, which have high flammability. Therefore, there has been a focus on introducing various flame retardants, but flame retardants can disrupt the formation of negative SEI films and reduce electrochemical performance. A recent study at the Pacific Northwest National Laboratory showed that unilaterally reducing the flammability of the electrolyte is not going to improve the safety performance of the battery, and that the exothermic reaction between the electrolyte and the charging electrode is the key factor in assessing the safety performance.That is, the non-flammability of the electrolyte is not necessarily the most influential parameter related to improving the safety performance at the battery level; the reactivity between the electrolyte and the charging electrode exceeds the flammability of the electrolyte. For the future development of safe electrolytes, achieving non-flammability in the electrolyte is only the start, but not the end, of improving the safety performance of lithium-ion batteries.
