What is a high rate battery?

In daily life, we often come into contact with high magnification batteries, such as in aircraft models, drones, and electric tools. They mainly rely on lithium ions moving between the positive and negative electrodes to work. During the charging and discharging process, Li+is intercalated and deintercaled back and forth between the two electrodes: when charging the battery, Li+is deintercaled from the positive electrode, embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium rich state; When discharging, the opposite is true. Batteries typically use materials containing lithium as electrodes. It is a representative of modern high-performance batteries. So what does the time rate and multiplication rate of lithium battery mean?

Time rate is the discharge rate expressed in terms of discharge time, which refers to the time it takes to discharge at a certain current and complete the rated capacity. For example, if the rated capacity of the Dongfeng brand EQl090E lithium-ion battery for 20 hours is 105Ah, that is, C=105Ah, the lithium-ion battery should be discharged at a current of 105 ÷ 20=. If it continues for 20 hours, it is considered qualified.

Multiplication refers to the value of a battery's discharge current being a multiple of its rated capacity value. For the EQl090E car lithium battery 6-Q-105 mentioned above, if the discharge current is expressed as, it is discharged with a current of=; If the discharge current is expressed as 3CA, it is discharged at a current of 3X105=315A.

Termination voltage refers to the minimum operating voltage at which the voltage of a battery drops to the point where it is no longer suitable to continue discharging. The discharge termination voltage is generally set lower under high magnification and low temperature conditions. Precautions for using high magnification batteries:

2. The heat dissipation of the carbon layer is inferior to that of aluminum foil, so it is necessary to make appropriate adjustments to the tape speed and baking temperature when coating.
