Tianjin University Professor Zhao Naiqin subject group and Tianjin Polytechnic University Kang established Professor, recently developed so far the thinnest of carbon nano materials with super thin film capacitor, the thickness of about 30 microns, only 1 / 3 of the A4 paper.
This is a distinctive feature of lightweight ultra-thin super capacitor. In order to obtain high performance devices, the research team from the design of device structure optimization, which has high energy density and power density. They used to chemical gas phase deposition method was prepared a flexible porous carbon nanofibers / ultra-thin graphite layer hybrid films, with solid electrolyte package two pieces of hybrid films get all solid state of self-supporting film super capacitor. After optimizing the structure design of the device, the whole volume energy density and power density than the reported similar Supercapacitive several orders of magnitude higher, the better performance, "build" a smaller but more "energy". The Supercapacitive per square metre weighs only 58 grams, and has good flexibility, if embedded into the clothes, can make clothes to power electronic products supply "".
According to reports, the capacitor also has deformation resistance and good cycle performance, charge discharge capacity remained above 96% after 5000 times. In addition, the super capacitor adopts solid-state design concept, not when it is subjected to impact or damage occurs when the liquid leakage situation. The super capacitor has long service life, fast charge and discharge and other advantages, and has good application prospects in wearable electronic devices and micro devices.
