Carbon Nanotube Batteries Pack More Punch

cremeglace writes "Researchers at MIT have come up with a new way of making batteries from carbon nanotubes. Carbon nanotubes are attractive materials for battery-making because of their high surface area, which can accept more positive ions and potentially last longer than conventional batteries. Instead of this design, the MIT researchers introduced something new — using chemically modified carbon nanotubes as the positive ion source themselves. For now, the new batteries can power only small devices, but if the method can be scaled up, the batteries may provide the power needed for applications like electric cars."

Yes, there are. High end golf clubs, tennis rackets and bicycles are starting to use carbon fiber enhanced with nano-tubes. It isn't 100%, but it is lighter and stronger than more traditional carbon fiber.

The problem is your source of information. Press releases aren't a very good source. If it's something you care about, look deeper like in a journal or something.
