Aniline tetramer-graphene oxide composites for high performance supercapacitors
Polyaniline (PANI), a promising conducting polymer for supercapacitor, exhibits high specific capacitance and good rate capability. However, it suffers from low cycling stability due to the breakage or scission of polymer ...
Insights on the fundamental capacitive behavior : a case study of MnO2
In this work, an insightful study on the fundamental capacitive behavior of MnO2 based electrodes is carried out using MnO2 hierarchical spheres (MHSs) and MnO2 nanoneedles (MNs) as examples. An overall understanding of ...
Nickel cobalt oxide nanowire-reduced graphite oxide composite material and its application for high performance supercapacitor electrode material
In this paper, we report a facile synthesis method of mesoporous nickel cobalt oxide (NiCo2O4) nanowire-reduced graphite oxide (rGO) composite material by urea induced hydrolysis reaction, followed by sintering at 300 °C. ...
Large areal mass, flexible and free-standing reduced graphene oxide/manganese dioxide paper for asymmetric supercapacitor device
Well-separated RGO sheets decorated with MnO2 nanoparticles facilitate easy access of the electrolyte ions to the high surface area of the paper electrode, enabling the fabrication of a thicker electrode with heavier areal ...
Achieving high rate performance in layered hydroxide supercapacitor electrodes
Layered hydroxides (LHs) are promising supercapacitor electrode materials with high specific capacitances. However, they generally exhibit poor energy storage ability at high current densities due to their insulating nature. ...
