(Phys.org)—A research group in China has discovered that the ink in an ordinary pen makes for a good coating when building a supercapacitor. The team, from Peking University (Beijing National Laboratory for Molecular Sciences) describe in their paper published in Advanced Materials, how they used pen ink to coat carbon fibers as part of a process in creating a supercapacitor that was not only bendable but able to cover a large surface area.
