Nanotechnology is awesome. Some researchers from Stanford University have found a way of using nanowire anodes in lithium ion batteries to great effect. These new wires are made out of silicon, which have a considerably higher charge capacity than the usual graphite anodes, but haven’t been used because their volume increases four times over when charged. Of course, for microscopic wires, four times larger still isn’t that big, and so pulverization can be avoided. After the patents get through and the manufacturers pick this technology up, you can expect to see much higher battery capacity in not only your BlackBerry, but all portable consumer devices, like laptops, MP3 players and video cameras. You can check out the full paper here.

This isn’t really very original. Altair Nanotechnologies developed a similar cell in 2005 and A123 Batteries also have a nano structure coating on their anodes. I am glad to see more players in this arena and the improvements that will result from the competition.
