Paper-thin, flexible, biodegradable battery created by Scientists
August 14th, 2007 by e-tech
It looks like Batteries are getting smaller and slimmer as scientists has invented a paper-thin, flexible, biodegradable battery,researchers from Rensselaer Polytechnic Institute and MIT have developed a new material that eliminates the need for a multilayer battery. They grew carbon nanotubes on a silicon substrate and impregnated the gaps between the tubes with cellulose—that’s right, plain old paper. The cellulose also covered the ends of the nanotubes, but once it had dried, the paper material could be peeled off of the silicon substrate, leaving one end of the carbon nanotubes exposed to form an electrode.
