How to understand high-rate polymer lithium battery

by:dcfpower     2021-03-24

High-rate polymer lithium battery, let's first understand the concept of rate. How to understand the discharge rate? Discharge rate refers to the current value required by the battery to discharge its rated capacity within a specified time. The data value is equal to the multiple of the battery's rated capacity, usually represented by the letter C. Generally speaking, if the C number is greater than 1, it is a high rate. High rate is a relative concept. The larger the C number of a lithium battery, the higher the rate of the battery.

The concept of polymer lithium battery

Next Talk about what is polymer lithium battery. Its full name is polymer lithium-ion power battery, which belongs to a kind of lithium battery pack. is a high-rate rechargeable battery, which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ is intercalated and deintercalated back and forth between the two electrodes: when recharging the battery, Li+ is deintercalated from the positive electrode and inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.

Combine high-rate and polymer lithium batteries, that is, polymer lithium-ion power batteries with a large discharge C number are high-rate polymer lithium batteries, and they generally do not It will be used in digital products such as mobile phones, but in the power systems of electric vehicles, various airplanes and remote-controlled model cars that require explosive power.

High-rate polymer lithium battery brand

High-rate polymer lithium battery pack requires a large discharge C number, but Not every factory produces a high rate of lithium batteries. There are various types of lithium batteries, and the batteries of lithium battery pack manufacturers are also very different. They have their own strategic and technological priorities. At present, the Grignard battery produced by the battery also has many high-rate polymer lithium batteries, and the battery life is relatively long, and it is well-known in the aircraft model industry for its battery cell technology and battery durability. In addition, there are some other brands of high-rate lithium batteries, which will not be introduced one by one again.

As we all know, the price of high-quality lithium batteries is not cheap, and the high-rate polymer battery has strong power, which provides racing power for competitive remote-controlled cars and model airplanes. The loss of the battery is also large, and the service cycle is shorter than other low-rate batteries, so it is also necessary to pay attention to the service life of these high-rate lithium batteries. It is a wise choice to choose those high-rate polymer lithium batteries that have a longer cycle of use.
