In modern society, batteries, as a widely used energy device, have penetrated into all aspects of our life and work. However, at the same time, the unqualified and safety issues of the battery cannot be ignored. In order to ensure the safety and reliability of battery products during use, the state has formulated a series of strict standards and requirements, including the GB31241 standard.
The GB31241 standard is a national standard formulated in China for the safety performance of portable battery energy storage products (such as mobile power supplies, lithium battery portable chargers, etc.). The main purpose of this standard is to ensure the safe use of portable battery energy storage products and prevent safety accidents caused by product design, manufacturing defects, etc.
Product composition analysis.
According to the GB31241 standard, we have carried out a detailed compositional analysis of battery products. Through precision instruments and technical means, we have carried out a comprehensive detection and analysis of the positive and negative electrode materials, electrolytes and other components of the battery. Our reports will detail the content and properties of each ingredient to give you a complete picture of the quality and performance of your product.
1. Cathode material: We have accurately determined the composition and content of battery cathode material through chemical analysis and physical testing.
2. Anode material: Similarly, we have tested the anode material of the battery to ensure that it meets the requirements of national standards.
3. Electrolyte: We use advanced analysis technology to test the electrolyte of the battery to ensure its safety and stability.
4. Other components: In addition to the above main components, we will also analyze other key components in the battery and provide you with detailed test results.
The main contents of the GB31241 standard include:
Marking and packaging: The product is required to have clear and unambiguous markings, including information such as product model, capacity, production date, safety warnings, etc., and the packaging of the product is required to be strong enough to protect the product from damage during transportation.
1. Battery performance: including battery capacity, voltage, cycle life and other performance indicators.
2. Charging performance: The product is required to have stable charging performance, and the charging efficiency must meet certain requirements.
3. Safety performance: including overcharge protection, overdischarge protection, short-circuit protection and other functions of the product.
4. Environmental requirements: The product needs to work normally under specific environmental conditions (such as temperature, humidity, etc.).
5. Test methods: The standard also stipulates the test methods of products, including performance tests, safety tests, etc.
