Using carbon nanotubes, researchers turn ordinary wood-pulp paper into flexible, resilient batteries
August 14, 2007
By weaving black carbon nanotubes into paper, engineers have created printable, flexible batteries that are more resilient than many existing batteries, yet can be cut, folded and worked just like paper. The rechargeable material could find uses in a range of devices, from portable electronics to automobiles.
Researchers from NSF's Nanoscience and Engineering Center for Directed Assembly of Nanostructures at Rensselaer Polytechnic Institute in Troy, N.Y., reported the new technology in the Aug. 13, 2007, Proceedings of the National Academy of Sciences.
In addition to withstanding a temperature range extending from minus 70 degrees Celsius to nearly 150 degrees above zero, the new batteries are capable of providing both the constant output of a standard battery and the sudden energy bursts of supercapacitors.
Because almost any liquid salt can serve as the electrolyte, the researchers demonstrated that substances found in sweat, blood and urine can help power the battery, making the system ideal for medical applications.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
