Hmm so that will be good when / if it can implemented, from what I read basicly the battery's will have longer cycle life I.e better then the 200-500 from current lions so will be much better, even more so in sealed lights with no replacble cells....and things like phones and tablets.
Also I'm not sure if I read it right but ten times increased capacity? WHOA? Imagine a 18650 with 5-10 times the current capacity...runtimes would be sweet even in high amp high output applications, can't even fathom what that you do for mobile computing and well everything....
There's a few interesting future techs in batteerys at the moment, liAir and its sodium equvilent, and super capacitors, ect ect...

Supercapacitors will always be dangerous as a removable power source, because they can discharge their entire charge instantly, which would kill a person. But yes, good things are on the horizon for battery technology.

Supercapacitors also have the disadvantage that their voltage drops linearly as current is drawn. And unlike the dropping voltage curve of LiCo batteries (which is not nearly as drastic, and which can potentially be improved, as it was when anodes were upgraded to graphite from charcoal), this drop is an inherent quality of capacitors (i = c * dv/dt). This means that any device using a capacitor as an energy storage device will REQUIRE regulation circuitry that can generate a constant voltage output. It may not be feasible from a cost or packaging standpoint to use such circuitry in all potential applications of supercapacitors. Additionally, while supercapacitors can supply high currents, the voltage regulation circuitry required to keep voltage constant will effectively limit this current in applications requiring constant voltage.
