Is there a correlation between the battery cycle life and the battery itself?

Power battery as the “heart” of pure electric vehicles, the key to pure electric vehicles is power battery. For power batteries, power battery performance indicators, capacity, service life and so on, are used to measure the performance of the battery, battery capacity in the long-term use of the battery will be reduced with the use of time, as a battery, What is the relationship between the number of cycles and the battery?

The number of cycles refers to the time and number of times the battery is in use, in other words, the battery is filled after the battery, then the battery is replaced, then filled again, in the light, and then filled repeatedly. For a power battery, a complete charge-discharge process is a cycle, according to this thing, the battery is cycle times.

According to the service life of the ternary lithium battery, the service life of the battery is about 1500 to 2000 cycles, and the number of cycles will decrease as the battery becomes less in the process of use, which means that the service life of the battery is also decreasing. In the process of use, because the number of cycles of the battery is decreasing, then it also means that the irreversible electrochemical reaction inside the lithium battery will lead to the capacity decrease.

Summary: the number of lithium battery life cycle is based on battery quality and battery material, the number of lithium battery cycle and battery life and so on is inextricably linked. Each cycle is completed a little less for the capacity of the battery and less for the life of the battery.
