Nanotubes may give the world better batteries

Scientists use thin films of multiwalled carbon nanotubes to keep lithium metal from sprouting dendrites, tentacle-like growths that can cause batteries to fail. The strategy could be key to developing batteries that hold more energy and charge faster than current, ubiquitous lithium-ion batteries.
