All of which Elon Musk says are fantasy, flawed, not usable in today’s build. I agree that we need dreamers, but that stuff has been going on since our grandparents were kids (see any old Popular Mechanics), and maybe one will emerge as a winner, but we a talking about mass market vehicle reduction. If the tech doesn’t exist today, you wont be driving it in the next ten years. The Tesla of ten years ago had no new tech, just assembled what was then 15-year-old tech, and their current cars are micro-evolutionary compared to ten years ago - and Tesla is arguably the game-changer - the most advanced in terms of having changed t R&D rules and forced the entire auto industry to change course. Yet the 18650 cell plus one step is still core to their cars and will remain so for the foreseeable future. They just made a commitment for billions more in 18650 cells.Whether something makes it to the market is certainly disputable but nothing in dream labs?
I am not in battery business but just googling stuff blows your mind on level of R&D going into this.
Claims 3X energy density increase, faster charging and longer life span.

Battery business is too difficult and complex for car companies to get into but they provide the demand to push universities to do the research and industry to make it happen. Power density is not the only thing that matters. If they can dissipate heat faster they can be used in cars and charging stations to significantly reduce charge time.
These guys say they can charge 70X faster so you don't need more range:

But if you do want more, getting twice the range is matter of combining different technologies. Mercedes EQXX does 700 miles on one 80 KWh battery charge.
Progress often happen gradually. We may not see 2X or 3X increase in one shot but over time, it may add up to that and more.
These guys are saying 50% more dense and 5 times more capacity:

on a more modest power density (20% - 40% improvement):

Mercedes EQG is already planning to use it in 2025.
Skeleton's 4X to 10X power dense super-capacitors (Graphene) can complement existing battery tech.
I listed these as dream lab examples not mass market ready to go. My point is too many of them are throwing dart at the board, some of them has to hit the bullseye. Even if non of them do, it is fun to watch them try.
