Stanford Pumps Li-Ion Batteries Up 10x
Researchers at Stanford University have made a major breakthrough in lithium ion (or Li-ion) battery technology. Utilizing silicon nanowires, a research group headed by assistant Professor Yi Cui has increased the amount of power generated by Li-ion batteries ten fold. Thus, a laptop battery that would normally run for 2 hours could run for 20 hours! These new batteries have been dubbed "High-performance lithium battery anodes using silicon nanowires."
This huge increase in power gives Li-ion batteries huge potential for other uses, such as electric cars as well as storage for solar power at home or the office.
Silicon expands as it absorbs energy, and thus previous designs caused it to break and weaken battery performance. The trick in Stanford's batteries lies in nanotechnology. Nanowires are in such a shape that when they expand from absorbing the energy, they still maintain their structural integrity.
"It's not a small improvement," Cui said. "It's a revolutionary development."
Fancy having a laptop with a battery lifetime of 20 hours?
