Researchers are developing new technology that  uses nano-technology to drastically increase the lifespan of batteries.

The key innovation involves using silicon nanowires instead of the usual carbon to store energy in a lithium-ion battery's anode.  Silicon has more than 10 times as much charge capacity as carbon. With this innovation, you could theoretically be running your laptop for 20 to 40 hours straight rather than the typical two to four hours. An electric car could go 400 miles on a charge rather than 40 miles. » read more
