Only not explicitly explained.
In short - it lasts the same as the battery of that capacity lasts today.
'In essence, we have developed a new generation of electrodes with new materials â" we call it MFE â" Multi Function Electrode," StoreDot CEO Doron Myersdorf told Gizmag. "On one side it acts like a supercapacitor (with very fast charging), and on the other is like a lithium electrode (with slow discharge). The electrolyte is modified with our nanodots in order to make the multifunction electrode more effective."
It's basically a supercapacitor on top of a battery.
You charge the capacitor quickly, it discharges into the battery slowly, and because the capacitor is actually a part of the electrode the loss is minimal.
On top of that, not having to discharge the capacitor into the battery all at once, it can discharge into the battery slowly, without heating it up, increasing the battery's life-cycle.
Discharge time is not the issue. Like others have already mentioned - we're gonna need new (thicker) cables and connectors to charge that fast.
And we just got the reversible USB.
