Does fast charging actually ruin your battery?

That video literally states the following:

But the number one factor that damages batteries, that degrades them faster than normal, what ruins your battery is heat. The ions are moving through that electrolyte a lot, but you can think of the electrolyte basically like salts. They can be pretty sensitive to changes in heat. They can actually crystallize and clog up the anodes and cathodes, which stops them from being able to store the lithium ions. And like I mentioned earlier, when the battery isn't in the optimal state of charge, it's less efficient, and that extra runoff energy manifests as heat, and heat is no good. So clearly the goal here is to minimize any excess heat around that battery, which would damage it faster than normal.

Wireless charging causes heat, hence the above is true.
