What is a high-rate polymer lithium battery

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 when the battery discharges its rated capacity within a specified time. The data value is equal to the multiple of the battery rated capacity, usually expressed 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, let's talk about what is polymer lithium battery. Its full name is polymer lithium-ion power lithium-ion battery, which belongs to a kind of lithium battery. Lithium battery is a kind of high-rate rechargeable battery, which depends on the movement of lithium ions between the positive electrode and the negative electrode to work. During charging and discharging, 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 via the electrolyte, the negative electrode is in a lithium-rich state; the opposite is true during discharge. Combining high-rate and polymer lithium batteries, it means that polymer lithium-ion power lithium-ion batteries with a large discharge C number are high-rate polymer lithium batteries. They are generally not used in digital products such as mobile phones, but are used in Those who want explosive power on the power system of electric vehicles, various airplanes and remote-controlled model cars.
