If it can charge in a minute, this means that the internal resistance of the battery is VERY low. Internal resistance limits how fast a battery can charge ...

but ...

it also limits how fast a battery can discharge. So, if this battery shorts (ie. water) this will discharge a lot of power in a very short period of time. This means that a LOT of heat will be generated.

Not saying this isn't a great invention; I am saying that there are going to be inherent dangers in this as well.

You've got a cloud for every silver lithium lining don't you?

Unless it has builtin diode-like limiting circuit, perhaps?

It would need some kind of internal fuse

Hmmm .. doing a little Google searching .. it seems that the discharge of these batteries can be precisely controlled, allowing for nearly infinite shelf life. Perhaps, just guessing, it could also allow for incremental discharging - only allowing a controlled portion of the surface area to discharge at a given time, limiting the output current, without limiting the recharge current.

This is not your fathers battery.

What part of this did you not read or comprehend?

A breakthrough technology applied to the negative electrode uses new nano-particles to prevent organic liquid electrolytes from reducing during battery recharging. The nano-particles quickly absorb and store vast amount of lithium ions, without causing any deterioration in the electrode.

The quick charging has nothing to do with the internal resistance.
