Batteries Use Nanostructure Materials to Generate Power
Nanomaterials provide the structure for batteries. Using carbon nanotubes researchers are able to infuse paper with the ability to make a complete battery with the carbon acting as the electrodes. Medical device researchers are looking to sweat or blood as a potential electrolyte. Thus, by touching the paper, a person makes the paper a complete battery system. Medical researchers see applications in implantable devices in which the carbon nanotubes could be implanted just below the skin so the human body becomes the recharge mechanism for powering a defibrillator for example.
Another nano technique is to use copper nanorods as the active material and attach them to sheets of copper foil. This increases the energy capacity by increasing the surface area of the nanorods.
Application of these technologies can be done with fairly traditional machines. In this example the nanorods are treated like fibers that can be woven into the fabric of a soldier’s uniform and can recharge itself.
Another technology in the research phase is electrowetting which according to Wikipedia uses nanostructured materials to combine the electrolyte material into the electrode space. mPhase proposes to use the technology to power semiconductor based devices through the use of superhydrophobic techniques which combines a liquid electrolyte and active electrode material.
