▍Certification Overview
Standards and Certification Document
Test standard: GB31241-2014: Lithium ion cells and batteries used in portable electronic equipment―Safety requirements
Certification document: CQC11-464112-2015: Secondary Battery and Battery Pack Safety Certification Rules for Portable Electronic Devices
Background and Date of implementation
1. GB31241-2014 was published on December 5th, 2014;
2. GB31241-2014 was mandatorily implemented on August 1st, 2015. ;
3. On October 15th, 2015, Certification and Accreditation Administration issued a technical resolution on additional testing standard GB31241 for key component “battery” of the audio and video equipment, information technology equipment and telecom terminal equipment. The resolution stipulates that the lithium batteries used in the above products need to be randomly tested as per GB31241-2014, or obtain a separate certification.
Note: GB 31241-2014 is a national compulsory standard. All the lithium battery products sold in China shall conform to GB31241 standard. This standard will be used in new sampling schemes for national, provincial and local random inspection.
▍Scope of Certification
GB31241-2014 Lithium ion cells and batteries used in portable electronic equipment―Safety requirements
Certification documents is mainly for mobile electronic products that are scheduled to be less than 18kg and can be often carried by users. The main examples are as follows. The portable electronic products listed below do not include all products, so products not listed are not necessarily outside the scope of this standard.
Wearable equipment: Lithium-ion batteries and battery packs used in equipment need to meet standard requirements.

Recently, China Electronics Standardization Institute, along with Zhongguancun ESS Industry Technology Association, held the forum of Sodium-ion Battery Industry Chain and Standard Development. Experts from research institutes, high schools and enterprises came to present reports about the industry, including the standardization, anode material, cathode material, separator, BMS and battery products. The conference shows the process of standardization of sodium battery and the results of research and industrialization.Oversea market: Transportation regulation of sodium-ion battery was established. E.g. UL standards already cover sodium batteries.The UN TDG created an identification number and name for sodium battery transportation. And chapter UN 38.3 also includes sodium based batteries.The DGP of International Civil Aviation Organization also issued latest Technology Instruction, in which it adds the requirement of sodium-ion batteries. This indicates that sodium batteries will be listed as dangerous goods for aviation transportation in 2025 or 2026.
