Nanotech ink turns paper into batteries

"Stanford University researchers have demonstrated a way to turn ordinary paper ito a battery, which may be crumpled or pressed into any form. It's said the technology promises greater durability, higher efficiency, and faster energy transfer than traditional batteries. The technique uses special ink made of carbon nanotubes and silver nanowires. Thanks to the small diameters of these materials, the ink sticks strongly to the fibrous paper, allowing the battery to be extremely durable. The paper battery could last through 40,000 charge-discharge cycles — at least an order of magnitude more than lithium batteries. According to the researchers, the paper batteries will be low-cost, may be crumpled or folded, and can even be soaked in acidic or basic solutions, yet their performance does not degrade. 'We just haven't tested what happens when you burn it,' one of the researchers quipped." For more information click on Paper Into Battery
