What is a high rate battery?

　　1. In our daily life, we are often exposed to high rate batteries, such as aircraft models, unmanned aerial vehicles, and electric tools. It mainly depends on lithium ions moving between the positive and negative electrodes to work. During the charging and discharging process, Li+is embedded and de embedded back and forth between the two electrodes: during the charging cell, Li+is de embedded from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium rich state; The opposite is true when discharging. Generally, lithium containing materials are used as electrodes for batteries. It is the representative of modern high-performance battery. What do you mean by the hourly rate and multiplying rate of lithium battery?

　　2. The time rate is the discharge rate expressed by the discharge time, that is, the time it takes to discharge the rated capacity with a certain current. For example, the rated capacity of Dongfeng EQl090E automotive lithium battery for 20h is 105Ah, that is, C=105Ah, then the lithium battery should be discharged at a current of 105 ÷ 20 =, and it is qualified if it reaches 20h continuously.

　　3. Multiplication means that the discharge current of a battery is a multiple of the rated capacity. For the above EQl090E lithium battery 6-Q-105, if the discharge current is expressed as, it is discharged with the current of=; If the discharge current is expressed as 3CA, it is discharged at a current of 3X105 = 315A.

　　4. The termination voltage refers to the lowest working voltage when the battery is discharged and the voltage drops to the point where it is not suitable to continue discharging. Generally, the discharge termination voltage under the conditions of high magnification and low temperature should be lower. Precautions for use of high rate battery:

　　1. Storage requirements: In an environment with a temperature of 25 ± 5 ℃ and a humidity of no more than 50%, the aluminum foil must be protected from air and water vapor during transportation;

　　2. The heat dissipation of carbon layer is worse than that of aluminum foil, so the tape speed and baking temperature should be adjusted properly during coating.
