The shortcomings of soft pack lithium-ion batteries are poor consistency, high cost, and easy leakage. The high cost can be solved through large-scale production, while leakage can be solved by improving the quality of aluminum plastic film. Structural characteristics of cyl...
Structural characteristics of soft pack lithium-ion batteries The key materials used in soft pack lithium-ion batteries include positive electrode materials, negative electrode materials, and separators, which are not significantly different from traditional steel and alumin...
The working voltage of 18650 lithium-ion batteries is generally 3.6V, 3.8V, and 4.2V, far exceeding the 1.2V working voltage of nickel cadmium and nickel hydrogen batteries. 6. High safety purpose 18650 lithium-ion batteries have high safety and use, do no...
How to control the temperature during the discharge process of rate based batteries is also a very important issue. During high current discharge, lithium-ion batteries will generate a large amount of heat, and the accumulation of heat inside the lithium-ion battery will lead to an increase in...
The niobium titanium oxide NTO new negative electrode material developed by Toshiba Corporation in Japan has a reversible capacity of 341mAh/g, which is much higher than LTO material and close to graphite material. However, with the advantage of high pressure solid density, the volume energy d...
① Material selection Generally speaking, improving the rate performance of power lithium-ion batteries is important from the selection of materials. At room temperature of 20 ℃, the electronic conductivity of LCO material is only 5x10-8S/cm, while the electronic conductivi...
4. CE certification The scope of application is in the European Union region, divided into safety and performance testing. CE certification belongs to self declaration. If manufacturers have the ability to conduct testing themselves, they can fully attach CE compliance labels to...
1. CCC certification The full name of China's 3C certification is the mandatory product certification system, which is a product qualification evaluation system implemented by governments in various countries in accordance with laws and regulations to protect the personal an...
Volume: The volume of a 12V lithium-ion battery needs to be determined based on its capacity, and there is no unified specification. The larger the battery capacity, the larger the volume Weight: Nowadays, many devices require lithium-ion batteries with larger capacity and l...
