Can this damage the battery?

Agree. My wife has an old MacBook Air, and its battery is fine. I had 2010 MacBook Pro that I killed about 10 years later when spilling water on the keyboard, and the battery was still working fine until it died. Well, "it didn't die like dead," just that the keyboard was shot (could not be used) so I didn't want the repairing trouble of a laptop that was already so old.

But as far as I know (you can correct me if I am wrong) in recent years new laptops manage the state of charge of the battery to extend its life span. In this case the battery is charged only when it needs charging.

Yea battery tech as come a long way, but Sleep mode has never been damaging to batteries. If anything it is probably good for them. Never using the battery at all is one of the worst things you can do.

+1. Long way since the early days of Ni-Cad batteries!

Arguably the biggest factor in overall battery performance and longevity.
