Home ? Renewable Energy ? How to Safely Transport Lithium - ion Battery - type (Power Bank) Products by Air

Due to the impact of global warming and the El Ni?o phenomenon, the high - temperature problem this summer has received much attention, especially the transportation safety issue. This article will focus on analyzingAir Transportationthe transportation safety issues of the most common dangerous goods - lithium - battery products (such as power banks), explore the internal and external factors that cause fires, and provide the classification and packaging requirements of lithium batteries.

I. Fire - causing Factors of Lithium - battery Products

Lithium - battery products, such as power banks, are common dangerous goods in air - transported luggage, and fire problems occur frequently.

Internal factors: The electrode materials and electrolytes of lithium batteries are flammable. Heating can cause fires and generate gases, increasing the possibility of battery explosions. Defects in the manufacturing process may also lead to lithium - battery safety problems.

External factors: Overcharging, external short - circuit, violent impact, etc. can all cause lithium - battery self - ignition.

II. Classification of Lithium Batteries

Lithium batteries are mainly divided into two categories: lithium - metal batteries and lithium - ion batteries.

In the International Air Cargo Dangerous Goods Regulations, lithium batteries are divided into four UN numbers, and each UN number corresponds to a specific type of lithium battery.

**Four UN numbers of lithium batteries**

Whether it is a lithium - metal battery or a lithium - ion battery, under normal use, it belongs to the category of dangerous goods and is a Class 9 dangerous good.

III. Packaging of Lithium - battery Products

The packaging of lithium - battery products is a matter of great concern in the lithium - battery transportation industry. The correct selection of packaging is particularly important.

Under normal use, the compliant packaging selection of lithium batteries (taking UN3480 lithium - ion cells/batteries as an example) at the international air - transportation stage should be in accordance with the requirements of the latest version of the Air Cargo Dangerous Goods Regulations IATA DGR (63rd edition).
