They look terrific ! I guess it will be some years before they appear in the hobby. I must admit I did check the date on the caption as its THAT time of year.

Only hold 2 volts at the moment but lets hope for progress.

Just seen a piece on Sky News about this, described as having massive potential (sorry ... no pun intended!) but very much in the early stage of development; possibly years away from the high street.
They also said that these new cells will be far more robust than lipo and similar technology, this was demonstrated by putting a drill through a cell which was under test; they will also be flexible.
Given the potential demand for a new technology I'm sure they'll be working hard to get it to market as soon as possible.

Looks like a good battery, if the testing and further R&D is fruitful.
Putting a drill through a battery that could potentially only hold 2 volts with no capacity rating stated isn't exactly demonstrating anything significant with regards to safety though. It could only be 10 mAh for all we know.

A basic law of physics is that you only get out what you put in. To charge a 2200 mAh battery in one minute you'd be charging at 60C, i.e. 132 Amps. A 5000 mAh pack would need 300Amps. Even if the battery costs are reasonable, we're gonna need some bigger, more expensive chargers!

Just thinking the same Phil!
However, I guess, just because you can charge it in a minute doesn't mean you have to. Even charging in 10 minutes would be fast compared to what most of us do now, and require a lower current, though still perhaps more than many chargers will deliver.
