Paper Battery

Stanford University researcher Yi Cui has developed a battery that is made by depositing an ink containing carbon nanotubes & silver nanowires on paper. He has previously done battery research using plastics but recently he’s found that the chemicals adhere much better to paper. The resulting battery or supercapacitor can then be folded, bent, rolled, and still work through about 40,000 charge cycles – twice the effectiveness of your standard Lithium Ion batteries.
