Nanotech Ink Turns Paper Into a Low-Cost Battery 129

jangel writes "Stanford University researchers have demonstrated a way to turn ordinary paper into 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." This is the same Stanford research team, lead by Yi Cui, whose work with nanotechnology for battery applications we have discussed before. We've also delved into alternate routes to the holy grail of the ultra-thin battery.
