It certainly could affect the tradeoff between battery weight and the need to avoid having to recharge. If you get a 70% charge in only 2 minutes as claimed, you might want a lighter product and be willing to live with the need for one recharge during the day . . .

The technology would see application in cell phones and tablets before cars.

I dunno, with the amperage and voltage calculations upthread, I don't see this coming to a home near you anytime soon, but rather at industrial-grade charging stations.

I agree, because cars are a pretty questionable application without an increase in energy density of no less than a factor of two.

Even so, this tech might make hybrid cars a little less impractical. Slashing the objection of high life-cycle battery cost would be a real plus. Could be that a smaller battery in your hybrid, deeply cycled, would actually work OK.

But I don’t understand a hybrid powered by gasoline; if you’re going hybrid you should exploit the flexibility of the electric energy storage/retrieval to make a really drivable diesel. If you are going hybrid you are going all out for fuel efficiency - and if you’re using a gasoline engine instead of a diesel to get fuel economy, you aren’t really trying.
