Do you remember Stanford scientist Yi Cui silicon nanowire anodes?
Well it looks like LG thinks that they might have a commercial product within 3 years..
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. When such a battery is charged, lithium ions move from the cathode to the anode. The new battery electrodes, described online in the journal Nano Letters, are anodes and can store much more energy than conventional graphite electrodes because they absorb much more lithium when the battery is charged.The silicon nanotubes are made by repeatedly immersing an aluminum template in a silicon solution, and then heating it and etching the structure in acid to remove the aluminum. "It's very simple, and the template is commercially available," says Cho. Along with LG Chem, Cho is working with the template manufacturer to make a template compatible with large-scale manufacturing. He believes batteries incorporating the nanotube electrodes could be on the market in three years.
