This is a bit misleading.

This doesn't apply to current batteries but rather some magical future battery which rusts. You can remove this rust with sound waves yet, removing the material would lesson its lifespan anyway, right? Since it doesn't undo the oxidisation process.

Not magical. One of the rules in this subreddit is to assume basic competence of the researchers. They have good reason to do this research.

How would this even work anyways? It looks like you'd have to take the battery out of the phone (which is a pretty big ordeal now), take the material out of the battery packaging, treat it and out it back together.

Seems hardly practical.
