The thing about new tech, batteries especially, is that most of the breakthroughs you hear about are in the lab or low volume.
Even if the claims are true then they have to find a way to make them at scale. Look how much trouble Tesla is having with the 4680s and that is a relatively minor change.
Then when you do figure out how to make them at scale there will initially be one factory making them which means there is only enough for a very limited number of vehicles and they will be expensive since the first factory / line will be small and a huge investment will have gone into it and the economy of scale will not be there. So those new superduper batteries will go into some expensive low volume vehicles and then one of two things will happen either a) the next you will hear is that they have all caught fire/been recalled/broken down etc OR b) they will be a major success and the maker will start to expand and or licence the tech and unless it can be built on existing production lines, which is unlikely, it will slowly filter into the market replacing existing tech from the top down over the course of 5+ years.
So there really is no such thing as an overnight disruption to battery tech. Its (ironically) like an oil tanker at this point , massive and takes time change course.
