From ArsTechnica:

A new version of lithium battery technology can either provide a higher storage density than current batteries, or can charge and discharge as fast as a supercapacitor, emptying its entire charge in under 10 seconds.

It's getting difficult to overstate the importance of battery technology. Compact, high-capacity batteries are an essential part of portable electronics already, but improved batteries are likely to play a key role in the auto industry, and may eventually appear throughout the electric grid, smoothing over interruptions in renewable power sources. Unfortunately, battery technology often involves a series of tradeoffs among factors like capacity, charging time, and usable cycles. Today's issue of Nature reports on a new version of lithium battery technology that may just be a game-changer.
