“…Pseudocapacitors can store more energy than EDLCs by higher utilization of electrode material. RuO 2 is the best pseudocapacitive material and has specific capacitance as high as 863 Fg −1 [5]. However, the high cost of Ru limits its commercial applications in electrochemical capacitors.…”

Nanostructured Co x Ni 1−x -Al layered triple hydroxides (Co x Ni 1−x -Al LTHs) have been successfully synthesized by a facile hydrothermal method using glycine as chelating agent. The samples were characterized by Xray diffraction, thermogravimetry, Fourier transform infrared spectroscopy and scanning electron microscopy. The morphologies of Co x Ni 1−x -Al LTHs varied with the Co content and its effect on the electrochemical behavior was studied by cyclic voltammetry and galvanostatic chargedischarge techniques. Electrochemical data demonstrated that the Co x Ni 1−x -Al LTHs with Co/Ni molar ratio of 3:2 owned the best performance and delivered a maximum specific capacitance of 1,375 Fg −1 at a current density of 0.5 A g −1 and a good high-rate capability. The capacitance retained 93.3% of the initial value after 1,000 continuous charge-discharge cycles at a current density of 2 A g −1 .

Poly-ether-ether-ketone (PEEK) is a high performance polymer with many intrinsic properties. When it is used in the form of coating, an improvement of some of its functional properties was achieved by forming a surface nanolayer. In this chapter, it will be described how it was possible to obtain this result. Firstly, three kinds of PEEK composite coatings were deposited by electrophoretic deposition, adding alumina particles, polytetrafluoroethylene (PTFE) and lignin to PEEK. Then, the composite coatings were thermal treated in a furnace. Therefore, surface nanostructure and chemical composition of these PEEK composite coatings were modified with respect to bulk coatings, due to interaction between PEEK chain and secondary phase, emphasised by the thermal treatment conditions. Experimental evidence of the formation of surface nanolayer was provided by SEM, TEM, GIXRD, ATR-FTIR and XPS characterisations. Functional characterisations demonstrated that wear resistance-in the presence of alumina particles-hydrophobicity-in the presence of PTFE-and corrosion resistance-in the presence of Lignin-were increased with respect to pure PEEK.

“…High power and long life cycle of electrochemical capacitors, which operate via taking advantage of the double layer formed at the interface of electrode and electrolyte [95], have made them a promising choice for energy storage applications [96,97]. The supercapacitor performance was significantly improved through EPD of hydrous ruthenium oxide particles with polytetrafluoroethylene (PTFE is a highly hydrophobic synthetic polymer) [44]. A schematic sketch of electrophoresis of these to particles can be seen in Fig.…”

EPD is a technique where charged particles in a stable colloidal suspension are moved through the liquid due to electric field and deposited on an oppositely charged conductive substrate, forming the intended material or device. EPD enables fabrication of a wide range of structures from traditional to advanced materials, from nanometric thin films to a fraction of 1 mm thick films, and from porous scaffolds to highly compact coatings. These structures include different compositions with complex shapes and structures which can be formed in a relatively short experimentation time by simple apparatus. This review presents the fundamentals, mechanisms, and characteristics of EPD along with its past and recent applications.
