Related standards of lithium ion battery at home and abroad

With the improvement and development of lithium-ion battery in materials and design technology, its application scope is constantly expanding, and the corresponding parameters are also higher and higher. To a certain extent, the safety is inversely proportional to the weight of lithium-ion battery, so with the emergence of large power lithium-ion battery, its safety index is also highly valued in the world. To develop lithium-ion battery technology, we must solve the safety problem. Lithium ion battery is usually safe under normal use conditions. The industry mainly focuses on how to ensure safety under misuse or abuse conditions. In the process of battery abuse, the thermal reaction in the battery can not diffuse in time, which leads to thermal runaway, and the phenomenon of air leakage, rupture, fire and so on. In order to ensure the electrochemical and physical safety performance of lithium-ion batteries (Li ion battery energy storage power supply), authoritative organizations at home and abroad have formulated various safety test standards for Li ion batteries.

international standard

The foreign standard system of lithium ion battery (lithium battery energy storage power supply) mainly consists of the following three types of standards:

1. International standards. Such as the International Electrotechnical Commission (IEC), International Air Transport Association (ICAO), the United Nations (UN) and other international organizations to develop international standards.

At present, the international standards for lithium-ion batteries are mainly IEC standards. In addition, there are also relevant standards, some of which are shown in table 5-4.

2. National standards or regional standards. Such as JISC, ANSI, BSI, DIN and en.

Foreign national and regional standards for lithium-ion batteries mainly include Japanese JIS standard, ANSI standard, German DIN standard, British BS standard and European EN standard. See table 5-5.

3. The standards of a standard setting body. Such as IEEE, UL and JBA. For example, IEEE 1625-2008 (multi cell rechargeable battery standard for mobile computing devices), uli642 and UL2054 of American Institute of insurance laboratories, JBA standard of Japan Battery Association, safety evaluation guide for secondary batteries.

Domestic standards

China's current safety standards for lithium ion batteries or product specifications with safety regulations are listed as follows:

1. GB / T 18287-2000 general specification for lithium ion batteries for cellular telephone;

2. GB / T 19521.11-2005 safety code for inspection of dangerous characteristics of lithium ion group dangerous goods;

3. GB / Z 18333.1-2001 lithium ion batteries for electric road vehicles;

4. YD 1268. L-2003 "safety requirements and test methods for lithium batteries for mobile communication handset";

5. SJ / T 11169-1998 standard for lithium batteries (EQV ul1642:1995);

6. QB / T 2502-2000 general specification for lithium ion batteries;

7. QC / T 743-2006 lithium ion batteries for electric vehicles;

8. Sn / T 1414.3-2004 safety inspection methods for import and export batteries Part 3: lithium ion batteries;

9. GB / T 24533-2009 graphite anode materials for lithium ion batteries;

10. GB / T 22084-2008 "batteries and batteries containing alkaline or other non acid electrolytes - Safety requirements for portable sealed batteries and batteries":

At present, the safety standards for lithium-ion batteries or the product specifications containing safety regulations to be submitted for approval are as follows:

1. GB / T 18287-201x general specification for file ion batteries and batteries for mobile phones;

2. SJ / T xxx-200x general specification for portable computer mobile power system.

The first standard is the revised version of GB / T l8287-2000, which is applicable to lithium-ion batteries for mobile phones; the second standard is applicable to lithium-ion batteries for notebook computers.
