Do you have other CATL slides? Source of this one?


Source: See comment on the following page:

RT Cycling = 100% charge and 0% discharge (complete cycle with deep discharge).

In general, if you do not charge more than 70% and you do not discharge by less than 20%, you can multiply the number of full cycle equivalent by 5.

Samsung will also release long-life batteries (30 years? : Shock: ), but rather intended for storage
