Crushed silicon can create a smartphone battery that lasts three times longer than current cells
ten times the amount of lithium ions than the graphic anodes commonly used with today's batteries. According to Motherboard, the result is a battery with 1000mAh per gram with 600 charge cycles of two hours charging, two hours discharging. Current graphite anone cells can handle only 350mAh per gram. The secret is the use of porous silicon that has more surface area than plain crushed silicon and enables the battery to hold more cycles. The porous silicon powder is mixed with pyrolyzed polyacrylonitrile. Besides the University, aerospace giant Lockheed Martin is also involved in the development of the battery.
We don't know about you, but for many this can't be commercialized soon enough so that those with an LTE enabled smartphone can stop looking for an electricity fix every few hours.

All the hue and cry over batteries in devices and all it takes is sand to solve our battery issues :)

There's been like 3 or 4 advancements like this in the past few months. It's great but I'd really like to see something actually happen with this tech. Come to market!

I agree with Captain_"D", advancements in the area of making longer lasting batteries have been in the news more and more as of late. Which is another reason i'm happy that my SG-Note has a removable battery. Bring on the sweetness of these longer lasting batteries... ;)

That's a great point. These batteries would probably be backwards compatible with phones today and with a removable battery you could just make the switch. So that's a selling point for another reason now.

Indian scientists are brilliant! Alas, they get necessary facilities only in other countries...
Nice invention! Hope to see it coming soon to phones.

I just imagined the next generation galaxy note (the current is still blowing my mind!), with a battery that lasts for two whole days under my itchy thumbs!

Get the "Will it Blend" guy over here. We need to make some batteries!
