Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices. The new version produces 10 times the amount of electricity of existing lithium-ion batteries. A laptop that now runs on battery for two hours could operate for 20 hours.
“It’s not a small improvement,” said Yi Cui, assistant professor of materials science and engineering. “It’s a revolutionary development.” The breakthrough is described in a paper, “High-performance lithium battery anodes using silicon nanowires,” published online in Nature Nanotechnology, written by Cui, his graduate chemistry student Candace Chan and five others.
