A A paper batterypaper battery is a battery is a battery engineered to use a paper-thin engineered to use a paper-thin sheet of cellulose (which is the sheet of cellulose (which is the major constituent of regular paper, major constituent of regular paper, among other things) infused with among other things) infused with aligned carbon nano tubes..aligned carbon nano tubes..

BENEFITS BENEFITS

The use of carbon nano tubes gives The use of carbon nano tubes gives the paper battery extreme flexibility; the paper battery extreme flexibility; the sheets can be rolled, twisted, the sheets can be rolled, twisted, folded, or cut into numerous shapes folded, or cut into numerous shapes with no loss of integrity or efficiency, with no loss of integrity or efficiency, or stacked, like printer paper to or stacked, like printer paper to boost total output. As well, they can boost total output. As well, they can be made in a variety of sizes, from be made in a variety of sizes, from postage stamps to broadsheets. postage stamps to broadsheets.
