There will never be a super-miracle battery. As you know batteries are governed by redox laws
, the Nernst Equation for one and there is a theoretic limit on battery performance. And that is around 2X what we have now IIRC. There are some papers on the web addressing this.
Secondly what MIT is doing is making lab demo devices. You know a couple of beakers with different solutions wired together. There is a huge gap between a benchtop demo and a production line and you probably know that better than I do.
And MIT and others, especially the Japanese schools, have been announcing wonder batteries for years now. We don't see any of them at the store when we go looking for some AA's. Why do they do this? Profs live by their research grants, wonder battery announcements equal research grant money. Period. Follow the money every time. I did see some new iron chemistry battery making it to the market. It is claimed to be an improvement over lithium but time will tell.
