In an advance that could help electric vehicles run longer between charges, researchers have shown that silicon nanotube electrodes can store 10 times more charge than the conventional graphite electrodes used in lithium-ion batteries. Researchers at Stanford University and Hanyang University in Ansan, Korea, are developing the nanotube electrodes in collaboration with LG Chem, a Korean company that makes lithium-ion batteries, including those used in the Chevy Volt.
