Disposable batteries play an indispensable role in modern life. They are widely used in a variety of devices such as remote controls, flashlights, toys, and other portable electronics. These batteries are generally favored by consumers for their convenience and low cost, however, safety issues are also a growing concern. In order to standardize the production and use of disposable batteries, China\'s national standard GB/T 8897.5 came into being.
MSDS, or Material Safety Data Sheet, is an important legal document that records chemical information. This specification is provided by the manufacturer or importer of the chemical and is intended to provide the user with comprehensive information on the physical and chemical properties, toxicity, environmental hazards and health effects of the substance. To ensure the safe use, storage, transportation and emergency response of chemicals, MSDS can not be underestimated.
Driven by globalization and technological advances, lithium batteries have become a key component in areas such as portable electronic devices and electric vehicles. However, the high energy density characteristics of lithium batteries also make them a potential safety risk during transportation.
Lithium iron phosphate batteries, with their high safety, long cycle life and environmental characteristics, are profoundly changing our lives. Today, from electric vehicles to home energy storage systems, the application scenarios of lithium iron phosphate batteries continue to expand, providing a strong driving force for clean energy transformation and sustainable development. However, lithium batteries also face huge safety challenges during transportation. In order to ensure public safety and environmental safety, the international community has developed strict lithium battery transportation standards, of which UN38.3 certification is a recognized entry threshold. Through the UN38.3 certification, it means that the lithium iron phosphate battery has the ability to cope with various potential risks during transportation, which is a strong proof of product safety.
The UL 2743 standard was developed by Underwriters Laboratories (UL) to test and certify the safety and performance of electrical products. The standard requires the reliability and durability of products in specific environments, ensuring their safety during use, especially the risk of fire and electric shock. The role of the UL 2743 standard includes providing manufacturers with design and testing guidelines to help them improve the safety and market competitiveness of their products. At the same time, the standard also provides consumers with a reliable safety guarantee, ensuring that the electrical products they use meet strict safety requirements. The implementation of this standard can effectively reduce the risk of accidents and protect the safety of users\' lives and property.
With the wide application of electronic equipment, button type secondary cells and batteries have been widely used in various portable devices because of their compact design and efficient energy storage capacity. To ensure the safety and performance of these cells and batteries, the International Electrotechnical Commission (IEC) has published the IEC 61960-4:2020 standard.
With the rapid development of the electric bicycle market, lithium-ion batteries have become an important power source for electric bicycles because of their high energy density and lightweight characteristics. However, the safety of lithium-ion batteries has been a focus for consumers and manufacturers. In order to regulate the production and use of lithium-ion batteries for electric bicycles, the Standardization Administration of China has issued the GB/T 36972-2018 \"Safety Technical Requirements for lithium-ion batteries for electric Bicycles\" standard. The main content of GB/T 36972-2018 standard The GB/T 36972-2018 standard mainly covers the safety technical requirements of lithium-ion batteries for electric bicycles, including material selection, structural design, manufacturing process, performance testing and so on. The standard clarifies the basic safety requirements of lithium-ion batteries for electric bicycles, such as the safety performance under extreme conditions such as overcharge, overdischarge, short circuit, extrusion, and high temperature. In addition, the standard also specifies the battery\'s labeling, packaging, transportation and storage conditions to ensure the safety of the battery throughout its life cycle. Safety requirements for lithium-ion batteries for electric bicycles 1, material selection and structural design: lithium ion battery anode and cathode materials, electrolyte, diaphragm and other key materials must meet the standard requirements to prevent the battery in the charge and discharge process of thermal runaway. The structural design should take into account the mechanical strength and tightness of the battery to prevent external impact and liquid intrusion. 2, manufacturing process: the manufacturing process should be strictly controlled welding, packaging and other key processes to ensure that the internal structure of the battery is tight, to prevent electrolyte leakage and internal short circuit. 3, performance test: The standard stipulates a series of performance tests, such as overcharge test, overdischarge test, short circuit test, extrusion test, high temperature test, etc., to verify the safety performance of the battery under extreme conditions. Companies should regularly perform these tests on batteries to ensure they meet standard requirements. Compliance requirements for lithium-ion batteries for electric bicycles 1, product identification: lithium-ion batteries for electric bicycles should be clearly marked on the product of the battery model, capacity, production date, safety warnings and other information, so that consumers can identify and use. 2, packaging and transportation: the packaging of the battery should meet the standard requirements to prevent collision, extrusion and other conditions that may lead to battery damage during transportation. Avoid adverse environment such as high temperature and humidity during transportation. 3, storage conditions: The battery in the storage process should avoid high temperature, humidity, direct sunlight and other adverse environment, in order to prevent the battery performance decline and safety accidents. Interpretation and suggestions of ZRLK As a third-party testing and certification body, ZRLK has a deep understanding and practical experience of GB/T 36972-2018 standard. We recommend that electric bicycle manufacturers manufacture and test in strict accordance with the standard requirements to ensure that the product meets the safety and compliance requirements. In addition, when buying an electric bicycle, consumers should choose battery products that meet the standards, and use and maintain the battery correctly according to the instructions to ensure their own safety. The implementation of the GB/T 36972-2018 standard is of great significance for improving the safety and reliability of lithium-ion batteries for electric bicycles. ZRLK will continue to be committed to interpreting and promoting relevant standards, helping enterprises and consumers understand and comply with standard requirements, and jointly promoting the healthy development of the electric bicycle industry. If you have relevant reporting needs, please contact ZRLK, we will provide you with professional testing and certification services.
In the era of rapid development of modern science and technology, battery as an important energy storage and supply equipment, its safety and reliability is particularly important. Especially in the field of outdoor energy storage, the safety of the battery is related to the user\'s personal safety and the long-term stable operation of the equipment. Therefore, the strict safety testing and certification of batteries, especially through UN38.3 (the United Nations Manual of Tests and Standards for the Recommendations on the Transport of Dangerous Goods, Part 38.3), has become an important standard in the industry.
