Analysis of Common Faults and Their Causes in Lithium-Ion Batteries

Introduce the Regulations and Precautions for the Transportation of Lithium-Ion Batteries at the Airport

Lithium-ion batteries are a common power source for a wide range of electronic devices, from smartphones and laptops to electric vehicles and portable power banks. However, due to their potential to overheat and cause fires, lithium-ion batteries are classified as dangerous goods and are subject to strict regulations when it comes to air transportation. In this article, we’ll introduce the regulations and precautions for transporting lithium-ion batteries at the airport, helping you ensure a safe and hassle-free journey.

Regulations for Transporting Lithium-Ion Batteries

1. United Nations (UN) Numbers and Proper Shipping Names:
   • Lithium-ion batteries are assigned specific UN numbers and proper shipping names to indicate their hazardous nature. For example:
     • UN3480: Lithium-ion batteries
     • UN3481: Lithium-ion batteries packed with equipment
     • UN3090: Lithium metal batteries
     • UN3091: Lithium metal batteries packed with equipment
   • These numbers and names help airlines and handling agents identify and handle lithium-ion batteries appropriately.
2. Lithium Content and Rated Energy Limits:
   • Lithium Metal Batteries: The lithium content should not exceed 2 grams.
   • Lithium-Ion Batteries: The rated energy should not exceed 100 Watt-hours (Wh). Batteries with a rated energy between 100Wh and 160Wh may be carried with airline approval, while those exceeding 160Wh are generally prohibited.
3. UN38.3 Testing Requirements:
   • Lithium-ion batteries must undergo UN38.3 testing to ensure their safety during transportation. This test evaluates the battery’s performance under various conditions, such as high altitude, thermal shock, and vibration.
4. Packaging and Labeling Requirements:
   • Packaging: Lithium-ion batteries must be packed in containers that meet the performance criteria for Class II packaging. The packaging should prevent the batteries from moving or being damaged during transport.
   • Labeling: Each package containing lithium-ion batteries must be labeled with the applicable UN number and a lithium battery handling label. The label should include the words “Lithium Ion Battery” or “Lithium Metal Battery,” as appropriate.
5. State of Charge (SoC) Limits:
   • According to the latest regulations from the International Air Transport Association (IATA), the state of charge for lithium-ion and lithium metal batteries is recommended to be no more than 30% until December 31, 2025. Starting from January 1, 2026, the state of charge must not exceed 30%.

Precautions for Transporting Lithium-Ion Batteries

1. Personal Use Only:
   • Lithium-ion batteries should be carried for personal use only. Commercial quantities may require additional documentation and approvals.
2. Prevent Short Circuits and Accidental Activation:
   • Spare Batteries: Spare lithium-ion batteries should be individually protected to prevent short circuits. This can be done by placing each battery in its original retail packaging or by insulating the terminals, such as by taping over exposed contacts.
   • Devices: Devices containing lithium-ion batteries should be protected from accidental activation. They should be completely turned off (not in sleep or hibernate mode) and protected from damage.
3. Prohibited Items:
   • Certain devices containing lithium-ion batteries, such as electric balance boards or hoverboards, may be prohibited from carriage due to their potential to overheat or catch fire.
4. Airline Policies:
   • Different airlines may have varying policies regarding the transportation of lithium-ion batteries. It’s essential to check with your airline before traveling to understand their specific requirements.
5. Safety Packaging and Labeling:
   • Ensure that lithium-ion batteries are packed in compliance with safety standards and that packages are correctly labeled with the appropriate lithium battery handling labels.
