A controlled surface exfoliation method for graphite pencil electrodes using an
environmentally friendly, low cost and scalable electrochemical process is reported. A …

Although Fe3O4 has high capacity, its low conductivity and poor cycling stability have limited
its application in supercapacitors. To address this issue, the core–shell structured Fe3O4 …

The enhanced power density, long term cycling stability, and fast rate of operation, makes
supercapacitors as desirable energy storage devices. Though metal oxides play a …

Abstract The ZnCo 2 O 4@ NiCo 2 S 4@ PPy core–shell nanosheets material is prepared by
directly growing leaf-like ZnCo 2 O 4 nanosheets derived from the metal-organic framework …

Hybrid electrode materials based on nanostructured metal oxide, conductive polymer, and
carbon derivative have promising properties for supercapacitors. Herein, a novel hybrid …

Polypyrrole (PPy) films were electropolymerized on pencil graphite electrodes (PGE). It is
usual that for supercapacitor applications composite materials containing conductive …

Biomass-derived activated carbon has been prepared from a bio-source (peanut shells) and
investigated as an electrode material for supercapacitors. The biomass-derived carbon was …

The most explored flexible supercapacitors based on PPy electrodes face a huge challenge
of poor cycle performance. Here, we demonstrate successful construction of sea urchin …

Polypyrrole (PPy) nanowires are widely used in supercapacitors due to their high faradaic
pseudo-capacitance and specific surface areas. However, their rapid capacitance …

Supercapcitors are prominent energy storage devices an account of its high-power density,
long cycle life and superior rate capability. Metal oxides play an important role in energy …
