Lithium-ion battery transportation packaging needs strict requirements, including the selection of seismic, compressive, waterproof, fireproof materials, the design of a stable structure, a reasonable layout of the battery, clear identification and labeling, and drop, vibration, waterproof, fire testing to ensure transportation safety.

As one of the indispensable energy sources of modern electronic products, the safety of lithium-ion batteries during transportation is particularly important. In order to ensure that lithium-ion batteries do not leak, short circuit, fire and other dangerous situations during transportation, the requirements for their transportation packaging are extremely strict. This article will elaborate on the requirements of the transportation packaging of lithium-ion batteries to ensure their safety during transportation.

First, the choice of packaging materials

The transportation packaging materials of lithium-ion batteries should have good shock-proof, pressure-resistant, waterproof, fireproof and other properties. Common packaging materials include metal, plastic, cardboard and so on. Among them, metal packaging materials, although strong and durable, but the cost is high and the weight is large, is not conducive to transportation; Plastic packaging materials are light, waterproof performance is good, but flammable and explosive; Cardboard packaging materials are cheap and easy to process, but the waterproof performance is poor. Therefore, when choosing packaging materials, the appropriate packaging materials should be selected according to the characteristics of lithium-ion batteries, transportation distance, environmental conditions and other factors.

Two, packaging structure design

The transportation packaging structure of lithium-ion batteries should be able to withstand the impact, vibration, extrusion and other forces during transportation to ensure that the battery does not suffer damage, leakage and other dangerous situations. Common packaging structures include wooden boxes, cartons, plastic boxes and so on. Among them, the wooden box structure is strong and durable, but the cost is higher and the weight is larger; The carton structure is light and easy to process, but the load-bearing capacity is poor; Plastic box structure is light, waterproof performance is good, but flammable and explosive. Therefore, when designing the packaging structure, the appropriate packaging structure should be selected according to the weight, size, quantity and other factors of the lithium-ion battery.

Third, packaging internal layout

The layout of lithium-ion batteries inside the packaging should be reasonable to avoid direct contact between batteries or squeezing each other to prevent the occurrence of dangerous situations such as short circuit and fire. Inside the packaging, the batteries can be separated by structures such as partitions and pallets to maintain a certain distance. At the same time, shock-proof materials, such as foam and air bags, should be set up inside the packaging to reduce the impact of shock and vibration on the battery during transportation.

Fourth, packaging identification and labels

The transportation packaging of lithium-ion batteries should be clearly marked with relevant identification and labels to facilitate identification and management during transportation. Common logos and labels include:

1. UN number: The UN number of lithium-ion batteries is 3480, which should be clearly marked on the package.

2. Dangerous goods label: According to the danger of lithium-ion batteries, 9 types of dangerous goods labels should be posted on the packaging to remind relevant personnel to pay attention.

3. Battery type identification: The type of battery should be marked on the package, such as lithium-ion battery, lithium metal battery, etc.

4. Battery number label: If the package contains multiple batteries, the number of batteries should be marked on the package.

5. Manufacturer information: The name, address, contact information and other information of the manufacturer should be marked on the package for traceability when necessary.

5. Packaging inspection and testing

In order to ensure that the transportation packaging of lithium-ion batteries meets the relevant requirements, packaging inspection and testing are required. Common inspections and tests include:

1. Drop test: drop the packaged lithium-ion battery freely from a certain height to test the impact resistance of the packaging material.

2. Vibration test: Through the simulation of the vibration environment during the transportation process, the stability of the packaging structure and the safety of the battery are tested.

3. Waterproof test: Soak the packaged lithium-ion battery in water for a certain time to test the waterproof performance of the packaging material.

4. Fire test: Through the simulation of fire environment, check the flame retardant performance of packaging materials.

Through the above inspection and testing, we can ensure that the transportation packaging of lithium-ion batteries meets the relevant requirements, so as to ensure the safety of the battery during transportation.

To sum up, the transportation and packaging requirements of lithium-ion batteries are strict, which need to be considered from the selection of packaging materials, the design of packaging structure, the internal layout of packaging, packaging identification and labeling, and packaging inspection and testing. Only transportation packaging that meets the relevant requirements can ensure the safety of lithium-ion batteries during transportation and reduce the occurrence of dangerous situations.
