This is the same stuff Altair Nano was pushing a few years back. We recharged them to 80%in less than 10 minute IIRC. They made a higher power/lower capacity prototype cell also that probably could have been recharged even faster.
The drawback was always energy density, at 80Wh/kg it's just slightly better than NiMH. The theoretical cycle life is in my opinion their biggest benefit and probably why they're targeting grid energy storage these days. As for cellphones the real limiter on how fast you can recharge tends to be the connector, cables and power supply.
