Performance of polyaniline/manganese oxide-MWCNT Nanocomposites as Supercapacitors
Composite electrodes of polyaniline/MnO2-Multi walled carbon nanotube (PANI/MnO2-MWCNT), MnO2-MWCNT nanocomposites and MWCNT was produced by the in situ direct coating approach. The supercapacitor performance of the nanocomposites was studied by Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). The electrochemical properties of electrodes were also investig...
متن کاملHigh-performance nanostructured supercapacitors on a sponge.
A simple and scalable method has been developed to fabricate nanostructured MnO2-carbon nanotube (CNT)-sponge hybrid electrodes. A novel supercapacitor, henceforth referred to as "sponge supercapacitor", has been fabricated using these hybrid electrodes with remarkable performance. A specific capacitance of 1,230 F/g (based on the mass of MnO2) can be reached. Capacitors based on CNT-sponge sub...

S are a unique type of high-power electrochemical energy storage devices being developed for a wide range of applications, including consumer electronics, medical electronics, electrical utilities, transportation, and military defense systems. However, the energy and power densities, safety, and cycle life of currently available supercapacitors need to be significantly improved to satisfy the r...
متن کاملCarbon nanomaterials for high-performance supercapacitors
Owing to their high energy density and power density, supercapacitors exhibit great potential as highperformance energy sources for advanced technologies. Recently, carbon nanomaterials (especially, carbon nanotubes and graphene) have been widely investigated as effective electrodes in supercapacitors due to their high specific surface area, excellent electrical and mechanical properties. This ...

Thus, the big challenge is in the nanostructure architecture where all of these parameters need to be optimized simultaneously. For the case of a supercapacitor, the nanostructure material is used as the framework to store and transport charges between two parallel electrodes. A conventional supercapacitor usually cons...
