Nanocomposites electrode

The lithium-storage properties of these Si SiOx/C nanocomposite electrodes were investigated in different electrolyte systems and compared to pure Si nanoparticles. From all the analyzed systems, the Si SiOx-C nanocomposite in conjunction with the solvent vinylene carbonate (VC) to form the solid-electrolyte interface showed the best lithium storage performance in terms of a highly reversible lithium-storage capacity (1100 mAh g-1), excellent cycling performance, and high rate capability (Fig. 7.9).

Apart from the insulating polymeric matrices, conductive polymers such as polypyrrole and polyaniline have been used as nanocomposite electrodes by chemical or electrochemical polymerization [13, 17, 116, 117]. Such materials provide high conductivity and stability. However, the use of insulating polymers can be more advantageous than the conductive polymers when employed in cyclic voltammetry.

Similar jirofitable effects of CNTs as backbones for nanocomposite electrodes have been shown with other pseudocapacitive oxides as nickel oxide [104].

The single-point attachment of DNA can also be achieved by chemisorption of thiolated DNA on nanoAu-GEC platform. The capability of surface regeneration of the nanocomposite electrodes allows repeated analyses with the same electrode.
