Sodium ion battery because of its cost and environmental advantages, the application range is more and more widely, the relevant regulations and standards are also constantly improving. Recently, the United Nations "Recommendations on the transport of dangerous goods model regulations" (hereinafter referred to as TDG) the 23rd revised edition has been published.
A set of testing requirements similar to those of lithium ion batteries and corresponding rules of use are stipulated, sodium ion batteries are required to meet the testing requirements of UN38.3, and clause 2.9.5 of sodium ion batteries is added. (Note: Lithium batteries are described in Section 2.9.4).
the hazard classification of sodium-ion batteries is the same as that of lithium-ion batteries, which are also classified as Class 9 dangerous goods. The new version of TDG adds two new UN numbers 3551 and 3552 for sodium-ion batteries, as follows:
UN3551 Sodium-ion batteries containing organic electrolytes;
UN3552 Sodium-ion batteries containing organic electrolytes are installed in or packaged with the device.
03 New Special Provisions
two special regulations SP400 and SP401 have been added to the transportation of sodium ion batteries. In addition, other special regulations and packaging guidelines originally applicable to lithium battery transportation requirements also apply to sodium-ion batteries.
Major changes related to battery-powered vehicles
01 Changes in UN Coding
vehicles or equipment previously operated by batteries are classified UN3171, The new version of TDG adds 3 new UN numbers for battery-powered vehicles, as follows:
UN3556, vehicles powered by lithium-ion batteries;
UN3557, Vehicles powered by lithium metal batteries;
UN3558, a vehicle powered by a sodium-ion battery.
02 Special provisions added
added SP404 and SP405. Among them, SP404 is only applicable to vehicles driven by sodium ion batteries. However, SP405 is applicable to all three new items. SP405 mainly stipulates that if the vehicle is not completely enclosed by packaging, crate or other methods that hinder identification, it can be exempted from the requirements of marking or labeling.
revised SP360 and SP388. Among them, SP360 deleted the provision of UN3171 applicable to vehicles powered by lithium metal batteries or lithium ion batteries, and replaced it with the three new entries above. SP388 Amend the scope of application to read: UN 3171 entry applies only to vehicles and equipment powered by wet batteries, sodium metal batteries or sodium alloy batteries, and the batteries are transported in vehicles or equipment. In addition, "when the vehicle is transported in the package, some parts of the vehicle (except the battery) can be loaded into the package separately from its main frame".
apply UN3556, UN3557 and UN3558. P912 stipulates that the vehicle should be fixed in a strong outer package, and the container structure should prevent accidents to avoid damage to the battery caused by the change of direction during vehicle transportation. It is clearly stipulated that the battery on the vehicle is not allowed to be removed, and the remaining parts can be removed to meet the packaging requirements. In addition, such goods do not need to carry out packaging tests, allowing packaging net weight of more than 400Kg. When the net weight of a single vehicle is ≥ 30Kg, the following requirements shall be met, namely:
(a) may be crate or fixed to a pallet;
(B) If the vehicle can be kept upright during transportation without additional support, and the vehicle provides sufficient protection for the battery so that the battery will not be damaged, it can be transported without packaging; or,
(c) If the vehicle is likely to overturn during transport (e. g., a motorcycle), it may be unpacked in a cargo transport unit with means to prevent overturning (e. g., using supports, frames or shelves).
