Could the lightweight discovery of electricity improve future devices?Paper, invented over 2,000 years ago, separated us of several objectives. Surprisingly, this widely used item was discovered for its ability to absorb films of carbon nanotubes and silver nanowires into its porous material to conduct electricity in a completely new way. However, paper is not the only object discovered for its ability to assimilate electricity. Viruses have also managed to conduct electricity and function like batteries. This discovery of electricity in a new, lightweight form led to questions about whether these objects could one day power large devices such as cars or help improve pacemakers located within a body. Could these lightweight discoveries in electricity improve future devices? Currently, Yi Cui and his team of scientists at Stanford University have discovered that it is possible to reduce electricity by producing "ink" made of carbon nanotubes. By simply coating a piece of ordinary paper with ink made from carbon nanotubes and silver nanowires, you can build a highly conductive storage gadget (Cui, Y., 2009). However, we can also simply make supercapacitors, which can store and discharge electricity much faster than a battery. In the future, paper supercapacitors could prove very useful for many large-scale applications, which depend on the rapid transfer of electricity. Thanks to this discovery, batteries made from paper can generate large devices such as electric or hybrid cars (PNAS, 2009). Compared to his previous research on creating energy storage devices using plastics, Cui's latest paper battery research showed that a paper battery is more durable than the middle of paper... ...Cui L., Cui Y. “Highly conductive paper for energy storage devices”.
