40 Hour Rechargeable Lithium Ion Battery
40 HOUR RECHARGEABLE LITHIUM ION BATTERY
January 29th, 2008
According to Popsci, researchers have crafted an lithium ion battery that's battery life lasts up to almost two days. How so? Apparently they incorporated silicon nanowires in the battery, which extended its life. The technology is still in the 'lab' stage.
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.
