Lithium Cells and Batteries Testing

Rechargeable lithium-ion batteries, the most widely used in modern digital devices. Fires and injuries from lithium-ion batteries have followed. State administrations for market regulation are very concerned about the quality of lithium-ion batteries. Civil aviation departments of many countries are also cautious about the transportation of lithium-ion batteries. Whether lithium-ion batteries comply with requirement of standard is highly concerned by manufacturers and users.

At present, the lithium-ion cells and batteries used in portable electronic products have implemented mandatory product certification management. Since August 1, 2024, the product that has not obtained the CCC certification and marked the certification mark may not be exported, sold, imported or used in other business activities.

Q&A

What is the difference between lithium cell and lithium battery?

A lithium battery pack is a combination of any number of lithium batteries containing a protective circuit.

What are the possible dangerous phenomena caused by lithium battery testing?

Leakage, deflating, cracking, fire and explosion, etc.

What are the requirements for portable electronic products in GB 31241 standard?

It should be less than 18kg of mobile electronic products intended to be frequently carried by users, such as portable office products, mobile communication products, portable audio /video products, etc.

For the battery pack, the above identification should be marked on the battery pack body. For the product whose structure can ensure that the user is not likely to misplug under any use, the polarity identification can be omitted. For the cell, the rated capacity, model and positive and negative polarity shall be indicated on the body. The remaining identification shall be allowed on the package or specification. However, if the manufacturer and the user agree, the cell used for the combined battery pack may not be identified.

How many samples are required for lithium battery testing comply with GB 31241?
