What kind of battery is a high-rate power lithium battery?

The high rate is related to the general rate and represents the charge and discharge capacity of the lithium battery. High-rate batteries are divided into discharge rate and charge rate. Use C to represent the ratio of the battery charge and discharge current, that is, the rate. For example, for a 10000mAh battery, 0.2C means that the battery is discharged at a current of 2000mA (0.2 times 10000mAh), and 1C means that a 10000mAh battery is discharged at 1 times the current of 10000mAh. If the battery supports a maximum current discharge of 20C, it is the battery label If it is marked with 20C stable discharge, the maximum allowable stable discharge current of this battery is: 200,000mA, 200A; the maximum current discharge of the battery is the discharge time: 10000mAhu003d10Ah, which means that it can be discharged for 1 hour when discharged at 10A, then 200A Current means that the time that can be discharged is 10Ah/200Ah×1 houru003d0.05 hoursu003d3 minutes; the difference between high-rate power lithium batteries depends on the C number that they support rate discharge, and the distinction is also based on the C number. Generally speaking , A high-rate battery that supports 10C discharge rate can be used by electrical equipment with lower discharge requirements than 10C, but it does not support electrical equipment with a higher current than 20C, otherwise the battery will be easily damaged. Therefore, for high-rate power lithium batteries, their specifications are divided according to the number of rates C that support discharge, and then the battery size and number are added. The following is the part of the processing and manufacturing of Grepp battery. In fact, high-rate lithium batteries are currently on the market. There are two types of high-rate polymer lithium batteries and high-rate lithium iron phosphate batteries that are commercially available. Because of their different processing and manufacturing raw materials, the range of rate discharge C numbers they can supply is also different. High-rate polymer lithium batteries can support a certain rate in the range of 1C to 120C for customized processing, while high-rate lithium iron phosphate batteries support a certain discharge rate within the range of 1C to 45C for customized processing. Although high-rate polymer lithium batteries are better than high-rate lithium iron phosphate batteries in supporting high-current discharge performance, they are not as good as high-rate lithium iron phosphate batteries in terms of high temperature resistance, safety performance and service life. At the same time, they are more expensive. It is also slightly more expensive. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
