CARBON NANOTUBE AND INDIUM OXIDE-BASED FLEXIBLE SUPERCAPACITORS

摘要

Supercapacitors are basically electrochemicalcapacitors that contain an unusually high energy density incomparison with normal, conventional capacitors. Asupercapacitor can temporarily store large amounts ofelectrical energy for release when needed. The use ofcarbon nanotubes (CNTs) in supercapacitors has beenattempted several times before; even graphite has beentouted as a potential material to create efficientsupercapacitors. Such attempts only resulted in creatingsupercapacitors with modest performances, in comparisonto those using transition metal oxide materials such as theoxides of iron, manganese, and rubidium. In terms of energystorage devices that are created using these supercapacitors,they are mechanically rigid and do not offer opticaltransparency. This severely limits their applications in theworld of flexible and transparent electronics. However, theuse of metal nanowires as a combination material with CNTsmay offer a different proposition for the designof superconductors.
