UN3481 is the United Nations (UN) transportation code for lithium-ion batteries, which is mainly used for identifying and classifying the transportation of lithium-ion batteries. The battery labeling rules are established to ensure safe transportation of batteries and comply with international regulations.

　　1、 Overview of battery labels

　　Battery labels are markings used to identify and identify lithium-ion batteries, and their design and use must comply with international transportation regulations and the requirements of the Air Transport Association (IATA). The battery label includes UN number, warning sign, battery category, symbol, and label.

　　2、 Label content

　　1. UN number: UN3481 refers to the transportation rule number of lithium-ion batteries, indicating that this is a type of lithium-ion battery.

　　2. Warning signs: The battery label should include warning signs to remind people to pay attention to the special properties and potential hazards of the battery. Common warning signs include flammable, explosive, toxic, and other signs.

　　3. Battery category: The battery label should indicate the category of the battery, such as lithium-ion batteries, nickel hydrogen batteries, etc. This can help people correctly identify the type of battery for appropriate handling and transportation.

　　4. Symbols: The battery label should also include some symbols to indicate the characteristics and performance of the battery. For example, positive and negative pole symbols, charging symbols, discharge symbols, etc.

　　5. Label: The battery label should indicate important information such as capacity, voltage, and model of the battery to facilitate people's understanding of the basic parameters of the battery. At the same time, it can also include information such as the manufacturer's name and contact information.

　　3、 Label specification requirements

　　1. The label should be clear and visible, not easily faded or worn. The background color of the label should form a sharp contrast with the surrounding background color to ensure easy recognition.

　　2. The label should be firmly attached to the battery and should not easily fall off. The adhesive of the label should have good adhesion and be able to maintain the integrity of the label under various environmental conditions.

　　3. The label should comply with international transportation regulations and the requirements of the Air Transport Association (IATA). This means that the size, color, font, etc. of the label need to comply with regulations to ensure its readability and effectiveness during transportation.
