Nanotech Anode Promises 10X Battery Life 193

UNIMurph sends word out of Stanford University that researchers have discovered a way to increase battery life tenfold by using silicon nanowires. Quoting 'It's not a small improvement,' [lead researcher Yi] Cui said. 'It's a revolutionary development.' Citing a research paper they wrote, published in Nature Nanotechnology, Cui said the increased battery capacity was made possible though a new type of anode that utilizes silicon nanowires. Traditional lithium ion batteries use graphite as the anode. This limits the amount of lithium — which holds the charge — that can be held in the anode, and it therefore limits battery life... 'We are working on scaling up and evaluating the cost of our technology,' Cui said. 'There are no roadblocks for either of these.'"
