With the rapid progress of technology, pure battery products have penetrated into every corner of our lives, from smartphones to electric cars, from smartwatches to drones, they have brought great convenience to our lives. However, there are certain safety hazards hidden behind this convenience, especially during the transportation of pure battery products. Especially under high temperature conditions in summer, there are many safety hazards when transporting pure battery products by railway. This article will provide a detailed science popularization and explanation on this.
1、 Characteristics of pure battery products
Pure battery products, especially lithium batteries, are the core power source of modern electronic devices. They have advantages such as high energy density, long lifespan, and portability, but at the same time, there are also some potential safety risks. The active chemical properties of lithium batteries make them prone to thermal runaway in high-temperature environments, where the heat inside the battery cannot be dissipated in a timely manner, resulting in a sharp increase in battery temperature. When the temperature exceeds a certain threshold, the battery may experience thermal runaway, leading to serious consequences such as fire and explosion.
2、 The Impact of High Temperature in Summer on Railway Transportation of Pure Battery-Products
Summer is a hot and rainy season, with generally high temperatures and humidity. This high temperature and humidity environment poses a great challenge to the transportation of pure battery-products. The following are the main impacts of high temperatures in summer on railway transportation of pure battery products:
High temperature environment: In summer, the internal temperature of railway transportation carriages may exceed the safe transportation temperature range of pure battery-products. This high-temperature environment will accelerate the chemical reactions inside the battery, increasing the risk of thermal runaway. In addition, high temperatures may also cause the electrolyte inside the battery to evaporate, further exacerbating the instability of the battery.
Vibration and shock: During railway transportation, trains undergo frequent actions such as acceleration, deceleration, and turning. These actions may cause pure battery-products to be subjected to vibration and impact. In high-temperature environments, such vibrations and impacts may exacerbate the instability of batteries and increase safety risks.
Poor ventilation: The ventilation conditions of railway freight cars are relatively poor, especially during high temperatures in summer, which can easily create a stuffy and hot environment inside the cars. This environment is not conducive to the heat dissipation of pure battery products, which may lead to an increase in battery temperature, thereby increasing the risk of thermal runaway.
3、 Why DG container sea and air transportation are more suitable choices
To ensure the safe transportation of pure battery products, we recommend using DG containers (dangerous goods containers) for sea or air transportation. The following are the main advantages of DG container transportation:
Temperature control: DG container sea and air transportation can provide better temperature control conditions, ensuring that pure battery products are within a safe temperature range during transportation. This helps to reduce the risk of thermal runaway and ensure the safety of pure battery products.
Vibration and shock protection: The design and manufacturing of DG cabinets fully consider the impact of vibration and shock. They use special materials and structures to reduce the damage of these factors to the battery, ensuring the stability of pure battery products during transportation.
Good ventilation: The DG cabinet has good internal ventilation, which is conducive to the heat dissipation of pure battery products. This helps to lower the battery temperature and reduce the risk of thermal runaway.
In summary, it is not suitable to use railway transportation of pure battery products under high temperature conditions in summer. To ensure the safe transportation of pure battery products, we should choose to use DG containers for sea or air transportation. This can better ensure the transportation safety of pure battery products and reduce the risk of accidents.
