UN 3536 designates lithium-ion orlithium metal battery packsfor installation in cargo units.
Fourteen new UN numbers have been added to dangerous goods Class 2 to Class 9, among which UN number 3536 is specified in dangerous goods Class 9 for lithium ions or lithium installed in metal cargo batteries. pack. This type of battery must be securely fixed in the internal structure of the goods transport device. It is not necessary to put a mark or transport label on the surface of the battery, but it is necessary to put a UN number and display plates on both. sides.
In the “List of Dangerous Goods”, 5 items have been deleted, 5 items have been added and 7 items have been revised. In Special Regulation 388, the UN numbers of the different types of electric vehicles and equipmentcontaining lithium batteries, sodium batteries, etc. are clearly specified: lithium metal batteries, lithium ion batteries, sodium batteries, etc., driven by flammable gas or liquid. Hybrid vehicles (UN 3166), lithium metal batteries, lithium ion batteries, sodium batteries, etc., pure electric vehicles driven by flammable gases or liquids (UN 3171), lithium metal batteries (UN 3091) installed in equipment and equipment Lithium-ion batteries in equipment (UN 3481).
What does un38.3 battery mean?
UN3480 must comply with the packing instructions of PI965, UN3481 must comply with PI966 (packed with the device) or PI967. (installed in the device's lithium battery) packaging instructions.
Lithium metal batteries (including lithium alloy batteries): lithium batteries with lithium metal or lithium alloy as anode, generaluse disposable, non-rechargeable batteries. Lithium metal batteries are often used in electronic watches, calculators, cameras, etc., such as button batteries.
Lithium batteries are generally divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation product of rechargeable batteries, lithium metal batteries, was born in 1996. Its safety, specific capacity, self-discharge rate and performance-price ratio are better than those of lithium-ion batteries.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It was invented by Edison. The reaction equation used by the battery is: Li+MnO2=LiMnO2. This reactionst an oxidation-reduction and discharge reaction. In the past, because the chemical properties of lithium metal are very active and the environmental requirements for processing, storage and use are very high, lithium batteries have not been used for a long time. With the development of modern science, lithium batteries have now become common. On February 22, 2016, ICAO announced a ban on checked baggage containing lithium batteries.
UN38.3 is a specification requirement proposed by the Special Advisory Committee on Transport as part of the joint meeting of the United Nations Standardization Organization and the Council economic and social, involving the safe transport of lithium batteries and related products. Once the battery meets the UN38.3 standard, this means that it has met a number of safety standards.strict tee. Tested and can be transported and used safely.
The UN38.3 standard contains many strict testing requirements, including thermal shock testing, vibration and pressure testing, etc., to ensure that the battery can work normally in various environments. work without causing safety problems. Additionally, batteries should have complete labels and instructions so that users can use and store the batteries in the right environment.
The importance of batteries complying with the UN38.3 standard
Compliance of the battery with the UN38 standard. 3 guarantees that the battery has passed a series of safety tests and can be safely transported and used under all circumstances. This is very important for both electronics manufacturers and consumers. It can make electronic products safer and reduce thehe risks and losses caused by battery safety issues. In addition, batteries that meet the UN38.3 standard can further improve product competitiveness and gain greater trust and evaluation from consumers.
