What are the dangers of lithium-ion battery goods in transportation?

What are the dangers of lithium-ion battery goods in transportation? Lithium-ion batteries have always been a 'dangerous molecule' in air transportation. During air transportation, lithium-ion batteries can cause high temperature and overheating due to internal and external short circuits. , Resulting in spontaneous combustion or explosion of the battery, the dissolved lithium ions from the combustion will penetrate the cargo hold or have enough pressure to break through the cargo hold wall, so that the fire can spread to other parts of the aircraft. What are the hazards of lithium-ion battery goods in transportation? With its unparalleled advantages, lithium-ion batteries are used in more and more fields. Marketing has become internationalized. At the same time, lithium-ion batteries are high-risk items. More and more attention is paid to the transportation safety of lithium-ion batteries, especially in summer in my country. High temperature and rain will easily have a greater impact on lithium-ion batteries. We must pay greater attention to the safe transportation of lithium-ion battery goods. The main dangers of lithium-ion batteries are as follows: Leakage: Poor design and manufacturing process of lithium-ion batteries or the external environment may cause the battery to leak. Check to ensure that the battery does not leak during transportation. Even if there is a packaging requirement Leaking liquid should also ensure transportation safety. External short circuit: If an external short circuit occurs, it is also dangerous. The temperature of the lithium ion battery will rise very high, and even fire or explosion may occur. It can be said that the external short circuit test is the most severe condition for lithium ion batteries after going through the harsh environment that may be encountered during transportation. Lithium ion batteries can meet safety requirements under this condition. The protection can eliminate this danger. Internal short circuit: The important thing is that the lithium-ion battery diaphragm is bad or the lithium-ion battery has small conductive particles entering and piercing the diaphragm during the processing, and the lithium-ion battery appears lithium-ion metal due to overcharging during use. Internal short circuit is an important cause of fire and explosion of lithium-ion batteries. Experiments should be conducted to change the design to reduce the danger of lithium-ion batteries. Overcharge: Overcharge the lithium-ion battery, especially continuous and long-term overcharge. Overcharge directly affects the stability of the battery plate structure, diaphragm and electrolyte, which will not only cause a permanent decrease in capacity, but also a continuous increase in internal resistance. Large, the power performance decreases. In addition, individual attenuated batteries will also have problems such as increased leakage, inability to store electricity, and continuous high floating charge current. Forced discharge: The over-discharge of the lithium-ion battery causes the structure of the negative carbon sheet of the lithium-ion battery to collapse, and the collapse will cause the lithium to be unable to be inserted during the charging process of the lithium-ion battery; and the overcharge of the lithium-ion battery causes too much lithium to be embedded in the negative carbon structure, As a result, some of the lithium can no longer be released, which will damage the lithium-ion battery. Summary: It can be seen that the safety risks of air transportation of lithium-ion batteries are particularly prominent. Lithium-ion battery transportation is a chemical product. Pay attention to waterproof, moisture-proof, and anti-exposure during transportation. Prevent high temperature and short circuit. In short, the transportation of lithium-ion batteries, whether it is passenger transportation, shipping, or sea transportation, has additional matters needing special attention. Everyone must strictly follow the rules and regulations during the transportation process to ensure the safety of the transportation link.
