Graphite material is abundantly available from recyclable sources. It possesses a good electrical conductance property, which makes it an attractive material as a working electrode. However, due to a high activation overpotential it has limited applications as compared to other solid metal electrodes. In this present work, we obtained a graphite rod from a used battery, and carried out electroc...

This paper proposes the idea of etching PZT to improve the temperature variation rate of a thicker PZT sheet in order to enhance the energy conversion efficiency when used as pyroelectric cells. A partially covered electrode was proven to display a higher output response than a fully covered electrode did. A mesh top electrode monitored the temperature variation rate and the electrode area. The...

In the current study, we report new flexible, free standing and high performance electrodes for electrochemical supercapacitors developed througha scalable but simple and efficient approach. Highly porous structures based on carbon fiber and poly (vinyl alcohol) (PVA) were used as a pattern. The electrochemical performances of Carbon fiber/GO-MnO2/CNT supercapacitors were characteriz...

Hierarchical heterostructures of NiCo2O4@XMoO4 (X = Ni, Co) were developed as an electrode material for supercapacitor with improved pseudocapacitive performance. Within these hierarchical heterostructures, the mesoporous NiCo2O4 nanosheet arrays directly grown on the Ni foam can not only act as an excellent pseudocapacitive material but also serve as a hierarchical scaffold for growing NiMoO4 ...

in this paper, the electrochemical hydrogen storage in nanocomposite materials was studied. multi-walled carbon nanotubes (mwcnts) electrode was prepared by mixing with special composite. the optimum ratio of mwcnts was estimated 30-70% (w/w) in the composite material. mwcnts were synthesized by chemical vapor deposition (cvd). the nanocomposite was homogenized by microwave. cyclic voltammetry ...

Conducting, boron doped diamond (BDD), in addition to its superior material properties, offers several notable attributes to the electrochemist making it an intriguing material for electrochemical research. These include the widest solvent window of all electrode materials; low background and capacitive currents; reduced fouling compared to other electrodes and; the ability to withstand extreme...
