Windows 7: New Breakthrough Paves Way for 10X Better Battery Life, Charge Rate

Despite its cutthroat nature, the mobile device market can be quite predictable in terms of innovation, which is mostly restricted to just a handful of areas. What’s more, most of the innovation that we see is evolutionary. But to quote late Apple founder Steve Jobs, “Every once in a while a revolutionary product comes along that changes everything.” That’s exactly the kind of breakthrough researchers at Northwestern University seem to have stumbled upon.

In a breakthrough that could have implications for everything from cellphones to electric cars, a team of engineers at Northwestern University have managed to improve energy capacity and charge rate in lithium-ion batteries by a factor of 10.

Maybe I missed it but the article seems to indicate that the battery's life will be extended 10X before it needs to be replaced. I didn't see anything stating that it will be able to provide 10X of usage time so I don't think you'll be able to get extended game play.

In a breakthrough that could have implications for everything from cellphones to electric cars, a team of engineers at Northwestern University have managed to improve energy capacity and charge rate in lithium-ion batteries by a factor of 10.

In current rechargeable batteries, the anode -- made of layer upon layer of carbon-based graphene sheets -- can only accommodate one lithium atom for every six carbon atoms. To increase energy capacity, scientists have previously experimented with replacing the carbon with silicon, as silicon can accommodate much more lithium: four lithium atoms for every silicon atom. However, silicon expands and contracts dramatically in the charging process, causing fragmentation and losing its charge capacity rapidly
