International shipping requirements and precautions for lithium battery products

International Maritime Lithium Battery Hazard Regulations On February 23, 2016, the World Civil Aviation Organization (ICAO) announced that from April 1, passenger aircraft will be prohibited from carrying lithium batteries. This is the latest regulation two years ago that banned passenger aircraft from carrying lithium metal batteries. This means that from April 1st, all lithium batteries and lithium metal batteries will no longer be shipped to passenger aircraft. The ban has also led to a more concentrated mode of transportation of lithium battery products than before, increasing the share of shipping by sea. Therefore, here is for us to interpret the relevant requirements and precautions of the 'World Maritime Dangerous Code' (IMDGcode) for lithium battery products. The meaning of lithium battery Lithium battery is a battery with lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution as the electrolyte. In the world of marine disasters, there are two types: lithium metal batteries and lithium batteries (including lithium ion polymer batteries). The important difference is that lithium metal batteries are non-rechargeable (such as button batteries), while lithium batteries are rechargeable (such as mobile phone batteries). The advantages of lithium batteries related to lead-acid batteries and other traditional batteries are mainly reflected in the following aspects. High energy, high energy storage density; long service life; high rated voltage; high power capacity; low self-discharge rate; light weight; high and low temperature adaptability; green. However, there are some shortcomings in the processing and application of lithium batteries, which are mainly reflected in the following aspects, as shown in Table 2. Table 2 Important Disadvantages of Lithium Batteries Lithium batteries have poor safety and high risk of explosion. Expensive; limited application conditions, high-temperature and low-temperature applications, high risks; high processing requirements. The requirements of the World Maritime Hazard Regulations for the transportation of lithium batteries In the 'World Maritime Hazard RegulationsThe risk category is Category 9 (Miscellaneous Risk Items). However, according to Section 2.9.4 of the Maritime Hazard Plan, lithium batteries (groups) and lithium batteries (groups) in equipment must meet the following 5 requirements before they can be transported, the most critical of which is the first one we know best Claim. In addition, for lithium batteries (including lithium ion polymer batteries) processed after December 31, 2011, lithium batteries installed in equipment or packaging equipment (including lithium ion polymer batteries) must also be marked on the outside of the watt-hour ratio. According to the special maritime risk code 348 rule. However, as long as the batteries and battery packs delivered for shipment fully comply with the requirements of the Special Provisions No. 188 of the Maritime Dangerous Goods Regulations, they are not subject to the Maritime Dangerous Goods Regulations and are shipped by sea as general cargo. Maritime hazard rules for damaged or defective lithium batteries during transportation. Damaged or defective lithium batteries generally refer to batteries or batteries that are considered defective for safety reasons, leaked batteries or batteries, and batteries or batteries that have suffered physical or mechanical damage . Such lithium batteries (packs) shall be marked with damage/defects of lithium battery packs or damage/defects of lithium metal battery packs during transportation. Any leakage of electrolyte should be absorbed by the inner packaging or the outer packaging to meet the slack adsorption data. For a single battery with a gross weight of more than 30kg, only one battery can be placed in each outer package. Other related requirements (see section 4.1.4.1 P908 or 4.1.4.3 section LP904). At the same time, under normal transportation conditions, batteries and battery packs that are prone to rapid differentiation, reaction danger, flame or overheating, toxic, corrosive, flammable gas or steam leakage risk, shall not be transported unless specified by the relevant authority.
