What is the life cycle number of lithium-ion batteries?

By huanggs
According to the quality of the rechargeable battery and the material of the lithium battery, the number of life cycles of the lithium-ion battery is determined:
  1. The ternary material lithium-ion battery can be cycled about 800 times.
  2. The cycle frequency of lithium iron phosphate battery is about 2500 times.
  3. The cycle frequency of rechargeable batteries is different from that of inferior rechargeable batteries. Fake and inferior rechargeable batteries are designed and manufactured according to the cycle frequency on the battery manufacturer's manual, and the cycle frequency of fake and inferior rechargeable batteries may not be easy sometimes. Appears within 50 times of a side.More:lifepo4 battery 500ah
The theoretical service life of ternary lithium batteries is about 800 cycles, which is above average among commercial rechargeable lithium batteries. The lithium iron phosphate battery has about 2,000 cycles, while the lithium titanate can complete 10,000 cycles. Today's mainstream manufacturers of lithium batteries promise to exceed 500 times in their ternary core specifications, but after lithium battery cells are assembled into lithium battery packs, due to consistency problems, it is very important to work The voltage and internal resistance cannot be exactly the same, and the service life of the circulation system is about 400 times. Under normal circumstances, the cycle frequency of the ternary lithium battery is about 500~1000 times. Assuming that the new energy vehicle drives 300km in a complete cycle, it means that after 150,000~300,000 kilometers, the battery life will be reduced. Circulatory frequency will be exhausted.understand more:48v 800ah battery There are many factors that affect the cycle life of lithium batteries, but the main reason is that the amount of lithium iron phosphate participating in energy transmission continues to decrease. It must be pointed out that the amount of lithium in the battery has not decreased, but less and less lithium iron phosphate has been activated. They are restricted to other places or in the channel of the activity, and cannot freely participate in the cycle of battery charging. process. Therefore, as long as you understand the movement of lithium iron phosphate that should participate in the redox reaction, you can figure out the principle of volume reduction, and you can also take certain effective measures purposefully to slow down the volume of lithium batteries. Reduce the development tendency and increase the service life of its circulatory system.
