If capacity is up x10 and they charge 10 times faster wouldn't the charge time be the same as it is now..The article states charge time in minutes not hours.
No. What this means is that the energy density is up 10 fold (IE, rather than the Galaxy S II having a 1.45Ah battery, it'll be able to have a 14.5Ah battery with no size increase). At the moment, batteries can be charged (generally) at 1C - I.E the Galaxy S II's battery can be charged at 1.45A normally without issue. Some more high performance batteries (those used in the R/C market for instance) can be charged at 10C, so a rate 10x that of the capacity. This battery technology is promising 10x the charge rate (the C), so it depends on which sort of battery they're comparing it with.
Charging a battery at 10C means for the SGSII you'd have to charge at 14.5A (or with the 10x capacity, 145A), which is far more than a USB port is designed to supply (1A @ 5V, which means current phones charge at less than 1C already). I can't see the charge rate increase being utilised by most consumer electronics, but it's nice to have if the technology could be used with electric cars.
