How many Cycle Life on CATL NCM Battery Moudle?

The cycle life of NCM lithium batteries produced by CATL is affected by many factors, including the number of charge and discharge cycles, usage conditions, etc. 

CATL produce 4S1P 14.8v 180Ah / 5S1P 18v 180Ah /6S1P 22.2v 180Ah NCM battery Module ,are very popular applied in EV .

The following is a detailed analysis based on the information provided:

1. Number of charge and discharge cycles: 

The theoretical number of charge and discharge cycles of ternary lithium batteries is about 2,000 times, and in some cases the theoretical value can even reach 3,500 times. 

This means that under optimal conditions, the battery can sustain more than 2,000 charge and discharge cycles without significant performance degradation.

2. Actual service life: 

In actual applications, taking into account battery consistency issues and other factors, the actual cycle life of ternary lithium batteries may be reduced to about 400 times. 

Therefore, if charging and discharging are completed every three days, the actual service life of the ternary lithium battery is about 4 years.

3. Life estimate: 

Although the number of cycles is an important indicator of battery life, the calendar life of the battery also needs to be considered in actual use. Some information mentions that the ternary lithium batteries produced by CATL can last for 8-10 years under standard use conditions. This estimate is likely based on a combination of the battery's calendar life and the number of charge and discharge cycles.

To sum up, the NCM lithium battery produced by CATL can sustain about 2,000 charge and discharge cycles under ideal conditions, and in practical applications, its service life is about 4 years. At the same time, depending on different usage conditions and maintenance, the calendar life of the battery may reach 8-10 years. These data provide a useful reference for understanding the life of CATL ternary lithium batteries.
