United Nations 《Recommendations regulations on the transport of dangerous goods 》(TDG) , promulgated in July 2017. It is a legal document specially formulated by the United Nations in the 1950s to regulate the international transport of dangerous goods, and also a basic document for the global transport of dangerous goods, its technical revision will have a far-reaching impact on the areas of sea and air transportation of dangerous goods.
There are two major revisions to the TDG regulations regarding lithium battery:
(1) Add 14 new UN numbers to class 2 ~ 9 dangerous goods, of which UN 3536 is designated in Class 9 dangerous goods as lithium ion batteries for use in cargo installations. Such batteries shall be securely fixed in the internal structure of the cargo handling device and shall not require a transport sign or label on the surface of the battery, but shall require a UN number and disclosure signs on both sides.
(2) 5 items have been deleted, five new items have been added and 7 special items have been amended from the dangerous goods list. In Special Regulation 388, the UN numbers of various types of electric vehicles with lithium batteries, sodium batteries are specified: lithium-ion battery, sodium batteries, etc, hybrid vehicle vehicles (UN 3166) , lithium metal batteries, lithium-ion battery, sodium batteries, the electric vehicles(UN3171) powered by flammable gas or flammable liquid, lithium metal batteries in equipment (UN3091) and lithium-ion battery in equipment(UN3481).
In addition, IATA (International Air Transport Association) made the 59th revision of Dangerous Goods Transport Rules, recently released a revised version of the content, many of which also involve lithium battery air transport. It is understood that the new rules will be implemented from January 2018. The main changes are as follows:
(1) Added isolation rules for lithium-ion batteries: Limit lithium-ion battery (UN3480, PI965 SectionI AorIB) and lithium-metal batteries (UN3090, PI968 SectionI AorIB), including explosives (Class1) , munitions (Division1.4S) , flammable gases (Division2.1) , flammable liquids (Class3) , flammable solids or self-reactive substances or solid desensitizing explosives (Division4.1) , and oxidants (Division5.1) .
(2) The total number of portable electronic devices carried by passengers or crew members shall not exceed 15 and the number of spare batteries shall not exceed 20.
(3) The height of the UN code in the lithium battery marker (lithium battery mark) shall not be less than 12 mm. In addition, the international maritime dangerous goods code ( IMDG CODE)38-16, issued by Internationalon Maritime Organizationtion, is enforced by China since 2018. Among them, P910 packaging guidelines have been added to those lithium batteries belonging to SP310 with low production capacity of less than 100 cells per year, which have not passed the test of UN38.3 and are transported for testing.
To ensure safe transportation for the lithium-ion battery, battery companies should:
(1)Pay attention to the new requirements of the UN regulations on lithium batteries timely, in particular the definition rules of the new UN number of lithium batteries and the transportation requirements of “Damaged/defective”lithium batteries.
(2) Pay close attention to the introduction time of new UN regulations by IMDG code and IMDG code, and adjust the packaging and documents of lithium batteries as soon as possible.
(3) Strengthen the contact with inspection and quarantine departments and cargo transportation organizations to understand the implementation rules of the new UN regulations, so as to ensure smooth shipment of lithium batteries for export.
In recent years, the frequent occurrence of fire accidents in lithium-ion battery production enterprises has led to higher authorities and industry associations to step up the management of safety in the production of lithium-ion batteries, for example, the Chinese chemical and physical power industry association has begun to develop lithium battery safety industry group standards. However, this is not enough, in addition to the production link, the transport link also needs attention. Because of the particularity of lithium battery, it is necessary to have the land transportation regulation based on its own technical characteristics, especially in the transportation of waste lithium-ion battery, which can not only ensure the transportation safety, it will also help promote the recycling of used power lithium-ion battery.
With the development of new energy vehicles, the electric vehicle battery have been driven, the scale of the lithium-ion battery will be bigger, the industry will have to consider the safety of lithium-ion battery transportation in advance, and the safety regulations for land transportation will need to be worked out as well, to ensure the safety of the lithium-ion battery.
