Flexible battery Recently developed a new technology for constructing the elements of power, which will make the battery flexible and, obviously, largely change the face of portable devices. New ultra-thin lithium-ion batteries are actually based on a sheet of paper - this way achieved properties such as flexibility and light weight. The results of the research were published in the journal ACS Nano scientists from Stanford University. According to the presented materials, the thickness of the ne w batteries can reach 300 micrometers. In doing so they have a high energy density and have functional advantages over other types of thin batteries. In order to create new batteries, Stanford experts on materials with hard base surface with a thin film of carbon nanotubes on top of which was covered by a layer of metal-based lithium. Thereafter, the resulting structure was placed on both sides of an ordinary sheet of paper. Thus, a layer of lithium acts as an electrode, while the nanot...
